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.

If you drive an open double-cab, stay under 80kph or face the law

Dear Baraza,
In your column last week, you mentioned that the Nissan Pathfinder is a dressed-up Navara. I could not agree more, and this remark reminded me of an experience I had with traffic police officers out to nab motorists exceeding the speed limit just before Naivasha on the Nairobi-Nakuru highway a while back.

I was flagged down for doing 100 km/h in an Isuzu D-Max Turbo double-cab pickup. My argument that a double-cab with all the LS trimmings is really a passenger vehicle and well within the 100 km/h limit fell on deaf ears.

The officer, credit to him, was civil and countered my argument by leading me to the back of my vehicle to show me a round sticker with ‘80KPH’ printed on it. This, according to the law, classified the double-cab as a commercial vehicle.

In the end other offenders and I were hauled to a police station, locked up in a wire mesh cell, and taken to court five hours later, where we were fined Sh2,000.

But this was after a passionate lecture by the base commander on the ills of driving over the limit. Incidentally, as we waited by the roadside, double-cab pickups fitted with those sleek canopies cruised by. According to an officer, those were SUVs!

In this era of common platforms (Navara/Pathfinder, Hilux/Fortuna, Ranger/Explorer, Tougher/Frontier, etc), where SUVs are built on pickup chassis, should the KMI not lobby for the reclassification of double-cab pickups to the passenger vehicle category?

The double-cab pickup is undoubtedly one of the fastest selling group of vehicles in the country today. Indeed, the trim and comfort levels of the top-end models put most saloon cars to shame. What is your take on this?

Tom

The policeman who busted you is either the new Sang (traffic police hero) or he was really idle. I am going with the first presumption.

Motor vehicle manufacturing is a wide field. Actually, the Pathfinder is not built on the Navara chassis, it is the other way round; the Navara is built on a Pathfinder plinth. That is why it is so good and feels very car-like, unlike the other double-cabs, which are dedicated commercial vehicles.

Some time in 2010, I wrote an article in which I argued that our speed limits were outdated and needed refreshing. My argument did not register with anyone.

Although I will admit it was unfair for the canopied pickups to drive by while your open-backed unit got flagged down, I must tell you that the police were unwittingly right: the covered vehicles were actually more aerodynamically stable than the open ones.

That payload area at the back acts as an air scoop at speed, and given the lack of weight over the rear axle, oversteer and extreme yawing will finally get the better of your steering input, and you will crash.

KMI, KEBS, the Transport Ministry, and anybody else concerned should compile a comprehensive list of what qualifies as a car, a light commercial vehicle, and a heavy commercial vehicle.

Anything from a 14-seater matatu to a tiny Maruti van requires reflectors, chevrons, and the “80KPH” sticker, but none of the Noahs/Voxys I see on the road has them. Why? Just because they do not serve as public transport?

Same to the pickups, more so the double-cabs; a good number of Navara and Vigo pickups do not have chevrons, and nobody seems to bother with them.

But try driving an ordinary NP300 or Hilux without them. Some of the SUVs we drive are actually heavier than the buses we (or our maidservants) use home, but the ordinary class E licence is good enough.

Hi,

I own a Toyota Corolla E98 with a 3E, 1469cc carburettor engine that has been leaking oil through one of the valves, but the mechanic insists that there is no problem.

The big blow came when it started mixing oil, fuel, and water. What is the main problem? I am thinking of changing the engine to EFI, so which will be the best for my car?

That aside, I have driven a Honda CRV Mugen and it is an amazing car in terms of comfort and fuel consumption. Which is the best Honda model in terms of comfort, fuel consumption, and maintenance costs?

Philip

That mechanic is a fraudster and knows not his trade. The problem is the valve seal of that particular valve — even an apprentice could tell you that.

The water could be from either a leaking gasket (replace) or one of the water jackets has cracked around the top, in which case a new engine block may be needed. The leaking water then mixes with the leaking oil, which in turn mixes with the intake charge to create the soup you describe there.

That Honda Mugen sounds like a real charmer, where can I find one for review?

Hello Baraza,
I have a question for you about Scania buses, since I use them to travel upcountry.

1. What makes them climb hills so fast (I am usually thrilled and fascinated when a bus shoots up with so much power that makes my whole body suddenly feel heavy and numb).

2. With this power, does it mean it can tackle any hill with varying angles/gradients easily?

3. If it is uses turbo, why does it change its sound when it begins to tackle a slope? The sound is like a continuous hiss and its engine generally does not sound like it is turbocharged.

4. Why do you never talk about nations that are leaders in auto engineering because Scania, which I heard is from Sweden, does not get highlighted and yet they have a good product?

1. Huge turbos and intercoolers boost the engine power and torque, the close-ratio short-geared transmission gives it good pulling power even on mountains, and variable valve timing and EGR (exhaust gas recirculation) improve combustion efficiency, give you lower fuel consumption, and reduce emissions.

Of course the engineers behind the engines are also the world’s best.

2. Err, not just any hill. But most of them, yes. It takes one roughly 15 minutes to go up the western escarpment of the Rift Valley (Salgaa-Mau Summit) in seventh and eighth gears (for the F330).

The Mitsubishis I see belonging to some bus company I will not mention take more than half an hour to cover the same distance, usually in third gear and making a lot of noise in the process.

3. The hissing (and for the old F94 HB, whistling or whining) sound you hear is the turbo spooling up and increasing boost pressure.

4. Sometimes I talk about these nations. Have you not heard me sing the praises of Germany more than once? Sweden is good in trucks — Volvo and Scania. Incidentally, the former bought out the latter from its parent company, Saab-Scania.

Their latest acquisition is Nissan Diesel UD commercial vehicles, so yes, even the UD buses are now relatives of their Scania competitors, by adoption.

Baraza,

Recently, you said that NZEs are a bit treacherous. Does the 1.8cc Toyota Luxel 16-valve VVT-i fall in that group too? If not, why? In terms of stability and reliability at speeds of around 120 km/h, how would you rank Toyota Allion A20, the new shape Premio, the new shape Caldina ZT, the Allex XS180, and the Luxel?

And what are the pros and cons of the 4WD types of the above mentioned cars?

Lastly, what are the pros and cons of having an auto or manual gear box in Toyota models, especially the saloons/sedans?

Fanon

Yes, the Luxel you describe is as treacherous — it is, after all, an NZE 120 (what we call NZE).

The Allion and Premio do not feel much different, but the Premio is smoother and quieter. The Caldina feels most planted (if it has a rear wing). The Luxel feels most dodgy, unsettled, and nervous (this is by comparison, it is not actually as bad as it sounds here), the Allex a little less so.

The pros of having 4WD models: good traction in the wet. The cons: increased weight and complexity of the transmission, hurts economy, and costs more to repair when damaged
Manual or auto?

Boils down to personal preference and proficiency with a clutch pedal. Some like manual transmissions (more control, fewer energy losses) while others prefer automatic (relaxing, any idiot can drive one).

Hi Baraza,

What is your take on the Cherry Tiggo vs the Land Rover vs the infamous Mahindra? There are plans by the Kenya Police to buy almost 800 of these vehicles (the Tiggo), can it withstand a beating like the Land Rover? I think the government is making yet another mistake on this procurement and someone needs to raise the alarm.

Ken

I would rather not delve into the procurement procedures of certain entities, least of all the police.

I know we do not live in the Nyayo era anymore, but I have a certain phobia for a white Land Rover parked outside my house at 2.30am with men in trench coats in my sitting room convincing me that a change in my career path would be most welcome for both the government and myself, or else…

Anyway, the Land Rover is the best of the three. The original police Mahindra is not even worth mentioning. The current Mahindra range’s performance and abilities are yet to be seen in hard use, but they are a damn sight better than the pioneers.

The Scorpio even looks like a Defender (if it is 2.30 in the morning and you have lost your spectacles, maybe to an angry man in a trench coat, and there are tears in your eyes…)

The Tiggo is a blatant RAV4 knock-off, but if other Chinese products are anything to go by, well, do not expect too much from it in terms of long service.

PS: The police thing is a joke, do not take it seriously. Nowadays, they visit people at 5 in the morning, not 2.30am.
