ROLLS-ROYCE WRAITH - IT'S A TRUCK: PH BLOG
What's in the Wraith's onboard fridge? Caviar? Champagne? Nope, a Yorkie bar
Yes, the Rolls-Royce Wraith's clever GPS-enhanced gearbox is in fact truck technology. Which is slightly less glamorous than the F1-inspired link Rolls-Royce claims. And will probably remain the one and only similarity one could ever draw twixt a Wraith and a Mercedes Actros.
To be fair if I hadn't had the benefit of a ride in a new Actros alongside Mercedes' ever-enthusiastic commercial vehicles PR man Simon Wood just before the show I'd have been as ignorant of its optional Proactive Powershift Control as anyone else outside of the CV world. But, just like the Wraith's SAT, PPC 'reads' the road ahead using proprietary 3D mapping and pre-selects gears accordingly, even shifting up before the crest of the hill at exactly the right moment for momentum to carry you over it. Mercedes reckons fuel consumption can be improved by as much as five per cent as a result, meaning a 'pay back' on the circa £1,349 cost within a year for a typical operator.
