This means we're asking the mighty 7L engine for only 1/3 of the torque that we're asking of the 1.8L engine, which is IIRC less than 25% of its available torque. The Aventador then is running at <10% peak BMEP...I think it's possible that 70mph could be better than 60mph in this car, despite the higher power requirement, because the engine efficiency is so much higher.
I don't know why people ignored my example, because the OP did ask for cars that got their best mpg at higher speeds.

Sorry I took so long to reply to this. I appreciate your response here, but my idea was to pinpoint the most economical highway commuter. The Aventador you speak of would most likely achieve it's peak economy at higher speeds than a normal vehicle, but may not be a cost effective commuter for me.
