Super-quick auto shifter



The 8-speed Amarok, does 0-100 in 10 seconds,
or any dune it sees anytime. Check the video.
FIRST off, a full disclosure: I am a Volksie fan — but in defence of the somewhat partial consumer advice that follows below, note I am not alone.
Last week, the VW Group, which includes VW, Porsche, Skoda, Seat, Bentley, Bugatti and Audi (which last year bought Italy’s Ducati motorbikes), announced it had delivered a record 9,07 million cars to customers during 2012.
But it was not in the interests of these millions of fellow Volksie fans that I speedily accepted VW South Africa’s invitation to a launch of the eight-speed auto Amarok on the dunes of the Namib Desert.
I did it for the family on my mother’s side, who farm sheep in the Karasburg mountains.
Tanned like mahogany, with sinews like steel, members on this side of the family don’t talk much, except when it comes to arguing which bakkie is the best dune rider.
For in the Namib, a farmer and his bakkie are only as good as the last dune they crossed was high.
Our host on the launch, none other than legendary racer Sarel van der Merwe, knows all this.
Which is why he was a bit worried about challenging a bunch of city-dwelling media — some still sporting milky white tans from the UK — to race the Amarok’s new auto box up a series of ever steeper dunes.
Matt Gennrich, general manager of communications at VWSA, however, had no doubts that VW’s eight-speed auto would empower even the most pallid of urban scribes. It has, after all, already proven itself in both Audi and VW sport utilities, albeit with faster gear ratios.
The divisional head for VW’s commercial vehicles, Jaco Steenkamp, explained that the auto box in the Amarok has a 4,8:1 ratio in first gear, which works as a low-range gear in off-road conditions, or when pulling a heavy trailer.
By comparison, Nissan’s five-speed auto box in the Navara, which was the first automatic 4x4 to impress me in the Namib, has a 3,827:1 ratio, which needs a bit more revs to go faster.
The lower ratios has also upped the Amarok’s towing capacity to match the three tons of the Ford Ranger and Mazda BT-50.
Steenkamp described the transmission, which has only five elements, and shifts using a torque converter, as “super-quick”, and he was not exaggerating. Whether racing up a dune or cruising along a dirt road, the rev needle stays in the optimal power band without the driver being aware of any shifting taking place.
VW combined the automatic box with VW’s 132 kW, 2,0-litre bi-turbo TDI engine, which is specced at Euro three emission standards and “easily lives with 500 ppm diesel”, according to Steenkamp.
He said VW’s Blue Motion technology can be fitted to make the Amarok even more economical, but then drivers have to ensure they tank up only with 50 parts-per-measure diesel.
The main features of BlueMotion Technology are the stop-start system and regenerative braking, which help fuel consumption and lower CO2 emissions.
Even in the Euro three spec, VW said the eight-speed box delivers a combined consumption of 12 km per litre, which puts the big bakkie on a par with tiny half-tonners.
The box also adapts to inputs from the driver’s right foot and will pull off in a higher gear whenever surface conditions and accelerator inputs allow. Foot-flat, VW said the Amarok can do 179 km/h in seventh gear and takes only 10,9 seconds to accelerate from zero to 100 km/h.
A Torsen differential, which locks at 1 800 revs, varies the 420 Nm to the front or rear wheels, as required.
The basic setting produces a 40:60 split, with 85% of the power sent to the rear wheels during cruising. Electronic stability control stays on permanently, but can be curtailed to aid dune driving.
The standard safety and convenient features available with the Amarok Double Cab Highline include electronic stabilisation control, with brake assist and hill start-hill descent assist and ABS, including off-road ABS.
That is no misprint: the Namib desert was 55 degrees Celcius
hot, but inside the Amarok, climate control ruled.
While these features sound like alphabet soup tastes, they do enable one to go down the steepest hill, in the deepest sand, using only fingertips to steer. Other active safety features include driver and front-passenger air bags and pretensioner three-point safety belts. Daytime running lights, 17-inch alloy wheels, a radio-CD that is MP3 capable with six speakers, dual-zone climate control, storage drawers under the front seats, cruise control and a 12-volt socket in the centre console, dashboard and load box, all come standard.
So are the three-year/100 000 km manufacturer warranty, a five-year/90 000 km Automotion service plan and six-year anti-corrosion warranty. The service interval is at 15 000 km.
As they did with the launch of the Amarok, VW South Africa kept the price competitive. The eight-speed Amarok sells for R461 100, which is a few tanks of diesel dearer than the competing Ford Ranger but cheaper that its badge twin, the BT-50.
