How can the naturally aspirated V12 of the Aston Martin Valkyrie LMH keep up with turbocharged rivals?

Question

Naturally aspirated V12 engine choice by Aston Martin for their Valkyrie LMH car is unique in a field of turbocharged powerplants. This will be a return to the golden age of motorsport, but leaves us wondering just how competitive it will be in today's endurance racing. They deliver power better and offer better fuel efficiency which is important in long distance events. But naturally aspirated engines can be more predictable in terms of power delivery and may also be more reliable. This will mean the Valkyrie’s V12 will have to work within the limited power output of LMH regulations, which will no doubt negate some of its high revving characteristics. Aston Martin's racing ambitions could either be a masterstroke or a significant handicap with this unique approach to engine design in the LMH class.

Come on, it’s probably more about promoting the road car than winning races. If it brings more attention to WEC, well, whatever, that’s cool.

@abhishek-r · Answer

That could be a genius move for balance of performance. An NA engine could be easier to adjust and balance against the turbo rivals.

@priyanka-r · Answer

I'm skeptical. LMH power limits prevent them from exploiting the V12's high rev potential to the maximum. They seem to be handicapping themselves with no real reason.

@charan-sin · Answer

It will be a fan favorite due to the sound alone. Sometimes that's worth more than some tenths of a second on the track.

@shinde-vik · Answer

This is a bold move that could prove reliable. A 24 hour race means fewer things to go wrong with fewer complex parts than a turbo engine.

@abhay-sing · Answer

Don't underestimate Aston's engineers. They could have some tricks up their sleeve to make that V12 competitive on fuel without losing the NA characteristics.

@varun-shar · Answer

The Achilles' heel will be fuel efficiency. They will be pitting more often, thus losing any performance advantage they might have.

@kapil-devs · Answer

Peak power is not the only thing. The V12 might be easier to drive and could also be more kind on tires as it might have a wider powerband.

@lokesh-goy · Answer

No way. The turbo engines have much more torque which is what you need to get out of the slow corners. The V12 will be left behind.

@anika-agra · Answer

Absolutely! The throttle response and power delivery of NA engines are better and more linear. That could be a huge advantage in tight sections and mixed conditions.
