For the third time, the fuel-pump attendant asked us if we were sure we wanted 95-octane unleaded for the bakkie. Even a very confident “yes” could not remove the puzzled look from his face, proof that diesel powertrains have taken over the bakkie scene. So, is there any reason to consider a petrol-powered double-cab bakkie?
The new 2,4-litre, naturally aspirated petrol unit features double-overhead camshafts and four valves per cylinder. It delivers 112 kW at 5 200 r/min and 233 N.m at 4 000 r/min. The latter figure is considerably down on those delivered by turbodiesel engines with a comparable displacement. Therefore, this petrol engine needs to be revved and the five-speed gearbox stirred to achieve good performance. Even so, it is more responsive than the KB250 D-TEQ.
However, its slight advantage is swept aside by the eyebrow-raising fuel-consumption figure of 13,5 litres/100 km. Could the choice of a petrol engine improve the refinement of the vehicle compared with diesel alternatives? Well, not really, because this unit is rough at higher engine speeds and does send a fair bit of vibration into the cabin. Maybe we have become so used to refined common-rail diesels that the difference to petrol engines is not as pronounced as 10 years ago.
Isuzu KBs are known for good ride quality and the KB240 is no different. Long-distance cruising is comfortably done and this bakkie confidently straddles the commercial/leisure vehicle line.
The cabin provides a decently put-together facia, although no soft-touch plastics are anywhere to be found. The increase in size of the sixth-generation Isuzu does provide more room, especially for second-row occupants. The driving position is good, although a reach-adjustable steering column would have been appreciated. Taller drivers complained that their shins would sometimes touch the underside of the dash when depressing the clutch. Radio, CD, USB and Bluetooth are provided, as well as a manual air-con system.
We took the vehicle to a picturesque off-road course in the mountains close to Somerset West and the KB240 proved itself very capable by conquering all the obstacles along the way. Good ground clearance and low-range in combination with a diff-lock helped to get the vehicle up very steep, rocky slopes with little fuss. Strange drivetrain noises were however noted, but could not be pinpointed to the diff or driveshafts. They may have been applicable only to our test vehicle.
Test Summary
As we now know, the sixth-generation Isuzu is an honest and capable vehicle without being a game-changer in the highly competitive bakkie segment. Brand-loyal customers who take the plunge will not be disappointed with their decision.
However, we advise you to choose one of the diesel derivatives. They offer better value in terms of economy and performance, and subsequently more driver enjoyment.
