Since F1 switched to its 1.6-liter V6 turbo formula for 2014, Mercedes-AMG has utterly dominated the sport—only now are rivals like Ferrari and Red Bull catching up. Following the debut of the AMG Project One road car, which uses its F1 engine, the team revealed some very intriguing details about this amazing power unit in .
Mercedes-AMG says that in Dyno testing at its Brixworth, UK engine factory this power unit can achieve over 50-percent thermal efficiency. In other words, this V6 can create more power than waste energy, which , makes it one of the most efficient internal-combustion engines on the planet. Motorsport also says that this engine can actually operate at similar levels of thermal efficiency as diesel engines used in large ships.
To better put that figure into context, AMG notes that F1's much-beloved old V10 engines only operated with about 30-percent thermal efficiency. When the V6 turbo era began in 2014, AMG's engine converted 44-percent of its fuel into power. With the increase in thermal efficiency between 2014 and now, AMG's power unit effectively makes 109 more horsepower using the same amount of fuel.
In the AMG Project One, this engine will be modified to run on regular pump gas, but it still should achieve around 41-percent thermal efficiency. That makes it more efficient than any other internal-combustion road car engine in production. Thanks to this, AMG boss Tobias Moers told us earlier this year that the Project One should run around the Nürburgring Nordschleife well over a minute quicker than an AMG A45 hatchback, all while using less fuel.
While it's easy to deride F1's latest engines as being a little soulless compared to their V8 and V10 predecessors, you can't deny that they represent amazing engineering feats. And with AMG's F1 engine headed to the Project One, some of this tech will finally be able to be enjoyed on the street.
