Woes might be a strong word… Mercedes-Benz surprised the car world with their then-named Project-One concept as not only did it look like it belonged in a prototype racing series but it was actually powered by an F1 engine.
The AMG Petronas turbo V6 engine was never designed as a street application powerplant. The main issue with the engine is not heat management as most would expect, it’s the idle. Unlike a road-car’s engine, this turbocharged V6 hums at 5,000 rpm. Its redline is 15,000 rpm. Both numbers are all kinds of wrong in a street-legal automobile.
Development, production and deliveries have been delayed by nine months because of this complication. As the Mercedes-AMG One is not a race-car, it needs to meet emissions too. Also, the engine needs to get along with a intricate hybrid system and a new gearbox.
Now that the issues are resolved, further development is underway and the first deliveries should occur sometime in the latter half of 2020.
