Autocar have discovered Porsche’s 919 Hybrid LMP1 car which Mark Webber will race this year will use a V4 engine with a single turbocharger:
The engine is a turbocharged 16-valve 2.0-litre direct-injection engine and has an unusually wide V angle, although the exact figure remains unknown. Unlike Audi’s LMP1 car, the turbocharger is not electric.
That is an extremely interesting solution for Porsche. I can’t remember any car that used an engine with such a configuration, either in motorsport or just for road use. And based on the article, due to the inherent difficulties of such a desing, it’ll be intriguing to see wether or not the Porsche powertrain will be as competitive as those of the competition. It just adds to the spectacular technical diversity in the world of the endurance racing, a thing I thouroughly enjoy!
