Driveability. Huge steps were made forward in this area from the 2015 debut to 2016, but Peugeot Sport has now ensured that the car's 3.0-litre V6 twin-turbodiesel engine is even more driveable for next year's Dakar, delivering greater torque at lower revs. Adding to the challenge for the engineers is the fact that the latest Dakar regulations have imposed a smaller restrictor on the engine (38mm as opposed to 39mm last year) with a net loss of around 20 horsepower. However, this power is now accessible from further down the rev range, meaning that the car is easier to drive and potentially even faster.
