This is really cool, but estimating 280HP at 2L when naturally aspirated has already been beaten. The party trick here is definitely the pneumatic valve control

This is really cool, but estimating 280HP at 2L when naturally aspirated has already been beaten. The party trick here is definitely the pneumatic valve control being able to switch combustion cycles on the fly. If you just want max power per liter, Nissan's 3 cyl from 2014 claims 400HP at 1.5L [0]. I'm guessing this high-output small engine tech will never come down to the consumer level since they all rev at 7-8k rpm. If there was a way to build a 3cyl SUV, I'm sure someone would have done it by now.

And Ford also used to have a 1.0L turbo I-3 in some models of Fiesta and/or Focus, although it was kind of obscure and may have only come with a manual transmission (in the US).
- VoxPelli 7y agoHere’s a 3-cylinder SUV from that other Swedish car manufacturer: https://www.autocar.co.uk/car-news/new-cars/volvo-adds-t3-three-cylinder-petrol-engine-xc40-range https://www.autocar.co.uk/car-news/new-cars/volvo-adds-t3-th... Also, the first Freevalve engine to be put presented in a car was in a normal sedan from a Chinese manufacturer: https://www.motorauthority.com/news/1107384_1-6-liter-camless-engine-delivers-230-hp-in-qoros-3 https://www.motorauthority.com/news/1107384_1-6-liter-camles...
- ska 7y agoThat Nissan is also turbocharged, so 280 isn't the right comparsion. you should compare 400hp/1.5L to 600hp/2l. Or perhaps 500hp/2l on regular gas - either way they are similar.
