The Tiggo will have criminals ‘shivering’ with laughter

Hi Baraza,
What is your take on the Kenyan government supplying police officers and provincial administration with the Cherry Tiggo cars? Are the cars the best they can use, considering that countries like the US use patrol cars that cannot be sold to the public, such as the Ford Victoria Crown and Dodge?

Is there any feature of the cars that can make criminals shiver at their sight? Are the cars meant for countries like Kenya, where most roads are not tarmacked? I think this was the reason behind the use of the Toyota Land Cruiser and the Land Rover.

Finally, are the Tiggos stable enough for high speed chases (like the Peugeot 504) or will they roll over, just like the military lorries do even at very low speed? I also fear that they may become old (lose shape) like the ones being used by the Chinese engineers constructing Thika road.

Walkins

You would be surprised that ex-police cruisers can be and are sold to the public in the US (after disarming them of the dash-stored shotguns and computers connected to security databases), especially the Crown Victoria and the Chevy Caprice.

The only reason criminals would shiver would be with laughter at the sight of the government’s cheapness in supplying Tiggos to the boys in blue. Not that they care, anyway.

The Chinese car would not be bad for the untarmacked roads, but their longevity is questionable. And gone are the days of the high speed police chase; nowadays they will just push a stinger into the path of the escaping felon and his goose would be well and truly cooked.

If and when the cops chase down the criminal, he could at least hope that the pursuit vehicle will age and break down some time during the chase (the reputation of China-sourced products).

Hi Baraza,

How does the Toyota Opa compare to the Toyota Fielder in terms of performance, handling, cost of maintenance, resale value, comfort, stability and power? I also want to know why you say the Opa is ugly and yet there are uglier cars, or is it just because beauty lies in the eye of the beholder?

Performance should be better than the Fielder, as is handling, but maintenance costs will depend on how well you take care of it. One on one, the D4 engine and the optional CVT transmission are harder to fix (and will thus cost more) than the equivalent VVT-i and auto/manual gearbox in the Fielder.

Resale value will be next to nothing, but if you can find a fellow Opa-lover, then all the best. Comfort: Very good, for the price and class. Stability: Better than the Fielder, but it is still not an F1 car. Power: 1.8 litre D4 performance, which means about 150 hp.

About its ugliness, just because there are other ugly cars, does that mean I should call the Opa pretty? If four students do an IQ test and one student gets a score of 1, and three others get 0, does that make that one student a genius? No, it is just that three other students happen to be less intellectually endowed. Same thing here; the Opa is still quite unsightly, whether or not Verossas and Wills exist.

Dear Baraza,

I want to move from a five- to seven-seater car to accommodate my family. Looking around, the following appealed to me because of looks, fuel economy, and parking space: Peugeot 307, Volkswagen Touran, Toyota Sienta, Honda Mobilio, and Nissan Cubecubic. I also visited CMC and saw the Maruti 800cc van.

What are your comments on these cars and which one would you recommend?

Muteti

From your list, I would say the Touran is the best seven-seater car. It is the most comfortable, has good power delivery, a six-speed gearbox, is highly versatile, and has Volkswagen’s bullet-proof build quality. Too bad it took an army friend of mine several attempts to get the gearbox fixed at CMC Motors before he was satisfied.

The 307 is also a good car, but with the French known to be unreliable, it may not be the best buy if you have resale value in mind. The Toyotas, Hondas, and Nissans are generic Japanese products that I am yet to assess (but I strongly suspect there is not much difference between them).

That 800cc Maruti is another thing altogether. It will seat seven people, yes, much in the same way back in the day my three sisters and I could fit in one red KP&TC telephone booth when making a phone call to daddy at work.

It is not an experience you will particularly enjoy or want to repeat daily. The Maruti is a small-capacity delivery van (mostly for pizzas or inter-office documents), not a Swiss family mobility solution.
Of the lot, I pick the Touran.

Hi,

What is the difference between the 2004/5 Lexus RX 300/330 and Toyota Harrier 240G/300G besides engine displacement? These cars are identical! Which would you go, considering spare parts availability and running costs?

Tony

Besides displacement, the only other difference is the logo in the grille up front. Such vehicles as the Toyota Harrier, Aristo, Altezza, Crown, and Land Cruiser Cygnus (the top-rung 100 VX model) existed because at the time the Lexus brand was not available on sale in Japan, so they were rebranded as Toyota.

Their respective Lexus equivalents were the RX 300, GS 300, IS 200 (and IS 250 in the US), LS 400, and LX 470. There was even a “Lexusized” J120 Prado called the GX 450.

In my world, availability of spares and running costs mean diddly squat, so I would go for the one with the biggest engine and the most horsepower and with the most apportionment (options like leather, climate control, and sun-roof).

For the cash-sensitive types, the diametric opposite of my desire is what they should settle for; the smallest engine with the bare minimum of optional extras.

Hi Baraza,

1. Between a 6-litre V8 engine and a 6-litre V12 engine, which one consumes more fuel? Is it engine displacement or the number of cylinders in the engine?

2. I have been seeing exotic modern cars (Aston Martin, Ferrari, Bentleys, Rolls Royce, etc) in Nairobi streets. Where are these cars serviced? It is not that I am aspiring to buy these cars in the near future, a turbo-charged Subaru is good enough for me.

1. Given the extent of automotive engineering thus far, it is neither of the options you list there. Genius and boffinry will determine the consumption capabilities.

Engine management (injection maps, variable valve timing), supplementary innovations (variable intake plena, active exhausts, use of forced induction, injector and plug placement/relationship, cylinder deactivation, charged gasoline injection, etc), the shape and design of combustion chambers, intake manifolds and exhaust manifolds, along with a whole lot of other things will determine the fuel consumption of an engine.

That is why the CL 65 AMG Mercedes-Benz coupe is a 600 hp monster that can still manage 11 kpl.

2. These vehicles belong to individuals who prefer to stay outside the scope of the public eye. I have seen them too. My presumption is that given what it costs to buy one (and the kind of brain power that goes into building one), it is only natural for the owners to send the vehicle back to the makers for servicing.

Either that or factory engineers are flown in with a complete tool kit to service the vehicle from the privacy of the owner’s home.

Hi,

I want to know about the work of the cylinders in a car and why they vary from vehicle to vehicle, for example, some have four while others have eight cylinders. Aside from that, you are always sceptical about the Cadillac Escalade and yet it is still one of the most prestigious vehicles today.

So how do you rate the Cadillac CTS-V in terms of performance, power (which I assume is quite a lot with the over 400 hp), comfort, stability, and fuel economy?

Three cylinders or less are typically used in less than 1.0-litre capacity engines (except the noisy tractor road-building equipment that uses just one but displaces more than 1.0 litre).

Four cylinders (in line) are good for fuel economy. V4 engines are noisy, and prone to vibrations, which requires the use of heavy crankshaft journals and flywheels to dampen the vibrations.

As a result, they make the car nose heavy, that is why they found limited use in cars. They are used for bikes, though. Horizontally opposed or “flat” four engines (H4) provide even weight distribution, and no, they do not wear the cylinders out on one side, as some people assume.

Five-cylinder engines are not much different from 4-cylinder ones.Most provide extra capacity without resorting to enlargement of cylinders. This applies to both V5 and in-line 5 engines. Six cylinder engines have legendary smoothness and good top-end (high rev) power characteristics.

That is why Lexus used them to great effect in their smaller saloons. The top-end power applies to both in-line 6 (Nissan Skyline GTR, Toyota Supra Mk IV, BMW M3) and V6 engines (Nissan GTR R35, Lotus Evora).

V6 engines have the added benefit of being compact, allowing for a more stubby bonnet or installation in a mid-ship platform, what we call mid-engined cars, or rear engine chassis.

Eight-cylinder engines develop huge torque. Straight 8s saw action a long time ago but these died a natural death. It was only sensible to make V8s. W8 engines were recently “discovered”, but since they involve the juxtaposition of two V4s, they do not get much airtime.

Twelve-cylinder engines have very good power and can rev to “abnormal” levels (the V12 in the Ferrari F50 road car could soar to about 10,000 rpm).

That is why they are used in top-end sports and performance cars (Lamborghini, Ferrari, top-flight Mercedes-Benz AMG and BRABUS cars). Sadly, the engine in the recently released Lamborghini Aventador will have the last automotive V12 to be used as manufacturers are now favouring turbo-charged V8s, which are simpler to build, more robust, and meet ever-tightening emissions standards.

Weirdly, some army tanks also use V12 engines, diesel powered. V10 engines share tendencies with V12s.

Beyond this point, most engines take a W configuration rather than V for the sake of length. The W12 engine (a creation of the VW Group and commonly found in Bentley and Audi) is just the mating of two V6s, side by side. The W16 (Bugatti Veyron) is the joining of two V8s.

The CTS-V is America finally waking up to the realities of life. The original 400 hp car was good (which is saying a lot for a Yank Tank), but the 556 hp supercharged version was great (this has never been said of any American car).

The blown CTS-V killed the BMW M5’s lap record for fastest four-door saloon at the Nurburgring, what with the M5 having two more cylinders (V10 vs the Caddy’s V8) and 50 less hp.

This war is not over. BMW have brought out a new M5 (the F10). They have gone back to V8 engines, they have lowered the engine capacity but (the trump card) to compensate for that, the M car now has two turbochargers slotted under the bonnet.

Initial reports indicate the car goes like stink and is so good it could end hunger in sub-Saharan Africa and bring peace in the Middle East — this is of course an exaggeration. The car will actually bring more war as each country fights to be the one supplying the unleaded that goes into the M5’s fuel tank.

A Subaru should not turn you into a revving idiot

Hi Baraza,

Thank you for the informative articles on motoring. I would like you to clarify something about Subarus.

Are they the strongest and most powerful cars around?

I am saying this because all the people I have come across driving Subarus are big-headed and arrogant on the road.

They go to the extreme of blocking your way when you want to overtake them, hardly give way, and they overtake at corners.

———————————–

No, Subarus are neither the strongest nor the most powerful vehicles around. They are not even the fastest.

These cars are fast earning a reputation for being the wheels of choice of indisciplined sociopaths, a rather sad state of affairs because the cars are quite good.

Buying one now, especially an STi (WRX or Forester, huge spoilers and massive exhaust in place) has become a social no-no; the law will watch you a bit more keenly and ladies will avoid you, suspecting that you are not as mature as you might look. Unfortunate.

But, no, Subarus do not turn you into an idiot.

Last Friday, I took one to Narok and back (Legacy saloon, black, two-litre, non-turbo) and, while the temptation to bounce off the limiter at 180 km/h was quite strong, I do not recall feeling the urge to privatise the road and inconvenience other users.

If anything, I remember being quite courteous, yielding more than I normally would.

————————————-

Hi Baraza,

I own a Subaru Impreza. Everything about it is okay but I am concerned because when I start the engine, the car smokes for about five seconds after which the smoke disappears.

I service the car regularly after every 2,500 km, so what might be the problem?

—————————————

Five seconds you say? Hmmm! ’Does not sound too bad, but all the same a car should never smoke.

What colour is the smoke? Blue means you are burning oil, in which case the valve seals may be leaking.

White smoke means you are burning coolant, so the head gasket may be leaking.

It could also mean you are burning ATF if your car is an automatic, so check the transmission seals for integrity.

—————————————-

JM,

We have a 2003 Nissan X-Trail and I am not comfortable with how the fuel gauge rapidly falls even when the vehicle is in 2WD mode.

We replaced the fuel filter and it is still bad compared to a normal Nissan X-Trail.

The mechanic checked and saw that the bonding record of the fuel gauge was up, not down, as it was supposed to be.

I request you to enlighten and advise me on what I am supposed to do.

1. Do I request the mechanic to kindly re-check it and try to correct it?

2. If not to re-check it, what could be the problem?

3. In your view, what should be done to correct the problem?

Thomas

————————————-

1. Yes, request the mechanic to have another look at it. Not necessarily kindly, unless you want him to do it for free, in which case, yes, request kindly.

2. The problem was identified: you said the issue was the irregular movements of the fuel gauge and you found an anomaly in the equipment, so through syllogism, it follows that the equipment is the harbinger of chaos on your dashboard.

3. Repair. Replacement. Anything that will get it working well again.

————————————

Hi JM,

I have owned a Nissan B15 for the past 11 months. Recently, it started to produce a strange sound from the engine.

My mechanic told me it has a slow knock and we bought motor honey for it.

What are the signs of a knocking engine and what measures should one take to prevent this?

Nyagah

————————————-

Motor honey? Anyway, signs of a knocking engine: first the oil warning light will come on, which means you should top up the oil (honey?) shortly.

It might go off and on a few times, or it might stay permanently on if you do not top up.

Depending on how hard, how far, and where you are driving, sooner or later a slight rattle will emanate from around the cylinder head area whenever the throttle is opened (off throttle, everything sounds OK).

If you can hear the rattle, then it is too late, you have suffered an engine knock.

To prevent an engine knock, always have the right amount of oil flowing through the engine.

Regular checks, especially before and after long/hard driving should be done to determine whether an oil change is due.

And always change the oil after wading through sump-deep water.

Hi,

I would like to buy a 2002 Peugeot 406, 1800cc. How would you rate this car and are its spares readily available?

Where can you service this vehicle in case you have it?

————————————-

This calls for a bit of research because I am not sure if Marshalls turned over all things Peugeot to Urasia, or if they still have stocks of old model Peugeot parts.

What I know is they are there. If these two do not have them, then good ol’ Grogan Road will.

I have found spares for my old 405 there on numerous occasions (and that silly thing is now 24 years old).

I rate the 406 very, very highly, and would buy one too once the money comes right. Servicing can be done at any garage of repute.

—————————————

Hi Baraza,

I own a Toyota Corolla NZE, which is a full-time 4WD. Please advise me on consumption as compared to a 2WD.

Secondly, someone told me that the gearbox for this kind of vehicle is difficult to repair in case need arises, that it is difficult to even transform from manual to automatic.

Please help me understand this.

————————————–

Consumption is just a touch higher in the 4WD, but you will never notice under ordinary driving conditions.

And yes, the transmission will be a swine to fix once broken because the marriage of the primary gearbox and secondary transfer case makes for an elaborate mechanical maze.

However, I am not so sure about the swap. It is usually easy in other cars, but I cannot declare anything yet until I study the schematics of the NZE powertrain.

—————————————-

Hi Baraza,

I own a Toyota Trueno and want to upgrade the carburettor engine to EFI.

It has a 1428cc 3A engine and I feel that the consumption is a little bit on the higher side (currently doing 10 kpl) so I want a more fuel efficient engine.

Should I replace it with a 6A or 5A Toyota engine? Which EFI engine is compatible with a 3A carburettor engine?

If I maintain the same carburettor power unit, how do I make it more fuel efficient?

—————————————–

The 5A is a better unit and you have a choice of two: the 5A-FE, for really good economy, or the 5A-FHE, which offers the economy but is tuned for a more aggressive output and better performance.

In order to maximise economy on a carburettor engine, the first thing you need to do is drive slower.

Then make sure the choke is in the correct position. If you want to get technical, you can fit smaller carburettors.

If you want to get really technical, you can swap the entire cylinder head for one of Honda’s CVCC heads, if you can find one, that is (this is technology from 1975, but it works like magic).

The CVCC engines have two-stage cylinder heads and two-channel carburettors.

One channel from the carburettor feeds a rich mixture into the upper combustion chamber, in which the spark plug is located, for easy combustion.

The other channel feeds a lean mixture into the lower combustion chamber, and the ignition heat from the rich mixture burning lights up the lean mixture, so the plugs do not have to be strained trying to ignite the lean mixture.

The result is almost 18 kpl from a 1.5 litre carburettor engine. Neat.

—————————————

Hi,

I am a part-time university student who is thinking of buying my first car.

I really admire the Land Rover 110 but know how costly they are. Recently, I found used ones that go for around Sh500,000.

Should I go for one and slowly change its looks by going for bodyworks and other stuff or should I purchase a different car that you would recommend, based on fuel consumption, maintenance, and resale value?

Griff

—————————————–

Griff, what do you want, or expect, from the Defender?

I also crave one too, just so you know, but fuel consumption and resale value are primary considerations for me, more so given that my heart is set on the petrol-powered V8 (it has a fearsome thirst, not even a loan from HELB could get you substantial mileage).

The diesel engines are a bit so-so. Anything pre-1999 is going to introduce you to the diametric opposite of a Lexus in terms of smoothness. And acceleration.

The petrol variants, on the other hand, will help clear your HELB loan faster than a feminist female classmate on a revenge mission against men.

There is a five-cylinder model that came out at the turn of the Millennium that might please you.

Turbocharged and intercooled, the 2.5-litre diesel can manage up to 11 kpl (avoid Thika Road at rush hour, if you catch my drift) and it can propel the Defender up to 140 km/h, at which point the laws of physics and nature take over to remind you that your car is not the last word in aerodynamics.

Maintenance sessions should fall within the “manageable” classification; not necessarily cheap, but thankfully far between, and the body construction of the Defender means prangs are easily cured by replacing the low-cost body panels rather than going for a hit-or-miss panel beating and/or repaint.

The addenda will cost you, though, especially those knobbly tyres. The exact costs will depend on what you want to add and what shop you buy it from.

—————————————-

Hi Baraza,

I intend to replace my Toyota Mark 2 (XJ100) 2000 model with a Mercedes S class W140, but my wife will hear none of it, saying Mercs are expensive to maintain.

But I know that Merc owners see garages less often than their Japanese vehicles counterparts, thus more savings in the long run.

Is there anything you can say to help me convince her?

Marto

———————————–

Yes, there is something I can add. It is a sad day when a woman chooses a Toyota over a Benz.

Suddenly, there is no need for us men to work hard any more if buying a Mercedes rather than a Toyota makes no difference to a woman — the woman we are trying to get on the good side of — or worse yet, she goes for the underdog Toyota. What gives?

———————————–

Hi Baraza,

I work in the automotive industry and regularly read your column. I wonder if your responses are based on facts.

You could be de-marketing some models, you know.

Nyambura Njuguna

————————————-

“De-marketing some models”? Mine is not to promote vehicle models, or demote them for that matter. I just answer questions.

And I should take exception to the fact that you suspect my responses are the product of pure conjecture or guesswork.

But I am good like that, so I will not.

The various franchises and dealerships/outlets have their respective PR and marketing departments, so I will not do their work for them.

I gain nothing by marketing one make of car over another without good reason to, or without supporting evidence; much in the same way I gain nothing by “de-marketing” others.

If the advice I dole out happens to hurt one brand over another, I am sorry, but that is from my various observations.

It is thus up to the respective PR/marketing firm/department of that company to do some damage control, and that does NOT include saying “Baraza JM (not Jim, by the way, as some people insist on calling me) knows not what he speaks”.

Please go over my answers again, carefully. You will notice that I answer questions according to how I am asked.

If a reader asks what the fuel consumption of a Cadillac Escalade is and I tell him “very poor”, it is because the Escalade is heavy on petrol: 4kpl is pretty whack, even for a lorry, and the Escalade WILL do 4kpl.

If a reader asks me what I prefer between a Land Cruiser and a Ranger pickup, I say Ranger pickup because I ACTUALLY prefer it to the Land Cruiser (but not to the Navara, incidentally).

If I do not know the answer to a question, I will confess my ignorance, as was the case over the Audi franchise holder.

What I know about are the horrors of posting untruths in a national newspaper: it is safer to say I do not know rather than publish nonsense for which I will take the flak, and what for?

As regards mechanical difficulties, mine is a consultation service, for which I charge my readers no fee; what I offer them is guidance or a starting point for them to solve their problems.

It may or may not work, but I am proud to say it mostly works.

Long story short, the answer to your query is yes, there is research behind my answers. And a personal touch too; I am human, after all.

And if you think I “de-market” cars, go watch a programme called Top Gear, you will thank me for how polite I am.

The Vista is Toyota’s answer to luxurious Cadillac saloon

At first glance, the Vista saloon looks like a hurried design job, with its short bonnet and stubby boot flanking a passenger cell gift-wrapped in an acre of glass and sheet metal, but the looks tend to grow on you.

The navy blue that our unwitting test vehicle came in does justice to its lines, and coupled with that chrome nose, it lends the car a regal appearance. Continue reading The Vista is Toyota’s answer to luxurious Cadillac saloon
