Stellantis CEO Gets Surprisingly Candid about ElectrificationIsn't the upcoming Mustang 4-cylinder an all-new engine? Don't know if that qualifies as new architecture but shows ICE R&D isn't dead yet.
I realize car guys are biased towards power and performance, but expect the average or typical buyer doesn't view 500 HP twin-turbo inline-6 (like the new Stellantis) the same way. I would love a naturally aspirated inline-6 as long as it had adequate power but wouldn't buy a twin turbo version. Ford has been very successful with V6 twin-turbo EcoBoost, but if I need that much power, I prefer a V8. Fuel savings don't justify added complexity for me. Perhaps GM came to same conclusion with new twin-turbo I-6 versus new V8? Report doesn't confirm the engine even existed, and can't confirm it has been cancelled, so not much there to start with.
I expect future ICE development will be focused more on fuel economy, so think new Atkinson engine is needed more for hybrid applications. A long-stroke naturally-aspirated Atkinson I-6 may have greater mass appeal for larger hybrid SUVs and pickups. A GM twin-turbo I-6 would seem mostly limited to ICE-only applications, so maybe not a wise investment at this point.Tue, 07 Mar 2023 16:01:38 +0000
