Sorento an AWD smoothy


WHEN The Witness drove the new-look Sorento in 2009, correspondent Gordon Hall was favourably impressed by the quick automatic shifting.
“It feels almost as if you are driving one of the new twin-clutch jobs — almost unnoticeable gear shifts with no noisy flare or slippage noise,” Hall wrote then. (The full report is available on www.scarletpumpkin.com.
 
Changes
In the past four years, Kia has kept the design of the Sorento the same, with what it calls “subtle tweaks that lead to major changes”.
“A millimetre on a brake disc can translate to metres on the road. A few degrees in suspension set-up can mean the difference between hot coffee on your lap or safely in its cup. Steering modified to be more responsive when you’re parking means that your alloy wheels are safe from pavements.
“This sort of innovative thinking and design is the difference between liking your car or loving the new Sorento,” its website states about the new Sorento.
Kia no longer sells a petrol model, with only a 2,2-litre turbo diesel available in either 4x2 or all-wheel drive. Both models come with all the trimmings, including seven seats, 18-inch wheels, xenon headlamps, a rear-view camera, a smart key with a stop/start button and self-levelling suspension. Our test model came with the optional sun roof as well.
Engine
As for the 2,2 diesel, it is like a vanilla-coffee smoothie, with a dash of bourbon. The common rail injection and 16 valves enable the overstroked engine to generate 436 Newton metres between 1 800 and 2 500 revs, and it can deliver this power at a peak work rate of 146 kW at 3 800 revs. (In the 4x2 model, power is strangely mapped at 15 Newtons lower.)
We often get asked what the difference is between 4x4 and all-wheel drive.
Compared to old 4x4s, the short answer in these days of electronic differentials and transfer casing locks with torque on demand is not much. Compared to new 4x4s, the answer is a hell of a lot, with in the likes of the new Iveco Daily 4x4, for example having five buttons just to lock axles in various configurations.
All-wheel drive (AWD) vehicles cannot lock axles and typically have low road clearances, but their modern diesel engines have so much low-down torque that as long as their sumps can scrape over the obstacles, new AWD vehicles can pretty much idle along routes that used to have signs reading “4x4 only”.
The 4x4 buttons in the new Unimog.
In comparison to all the buttons that need pressing in a proper 4x4 such as a Unimog, AWD systems do the thinking for the driver, forcing the front and rear axles to turn slower or faster in relation to each other, depending on how much wheel spin the electronics detect.
When the going is smooth, AWD systems typically send all the power to the front wheel.
The Sorento does likewise, which all helps to get good fuel consumption for a 2,5 ton car.
Ability
To test the AWD abilities of the Korean, I took the Sorento into the Valley of a Thousand Hills, to see first-hand how sand is being pillaged from the Duzi River’s banks.
On a muddy patch, the AWD computer diverted power to the rear axle as soon as the front wheel started slipping.
But with a low road clearance of 18,4 cm, and independent suspension that allowed limited wheel travel between the long nose and boot, I did not risk going off the Jeep tracks into softer sand, having once spent a sweaty afternoon digging out a similar vehicle after it got stuck.
Comfort
On dirt roads the ride is firm, with climate control and good ergonomics, ensuring that some passengers got so comfortable they started snoring.
The reassurance provided by six air bags may have had something to do with that.
The only complaints were from the rear passengers, who struggled to see out of the relatively small windows, and from the small ones on the fold-up seats in the far rear, who complained that the sun was getting too hot through the back window.
Pricing
The Sorento costs R480 000.
It’s main competitor comes from the same factory in Korea, the Hyundai Sante Fe, which offers three models ranging in price from R449 000 to R520 000.
Other seven seaters on sale in SA include the likes of the Toyota Fortuner and the Mahindra Xylo, neither of which can match the Koreans for power, creature comforts or price.
