Not to knock 96 mpg at any speed but the headline is rather more impressive than the claim in the article.
- cynicalkane 14y agoYup. This is a common pitfall when talking about European cars. They're sometimes quoted in Imperial MPG even when they're not for sale in Britain.
- TylerE 14y agoNo, that's not the flaw (although it is true). It can get 96mpg. It can go 100mph. It _cannot_ do both simultaneously.
- thwest 14y agoThe more fundamental flaw is how to drive _on_ a mile per gallon rate.
- cynicalkane 14y agoThanks, didn't read closely enough and it's too late to edit. :)
- nollidge 14y agoSo it's 80 MPG U.S.
- moreati 14y agoI think avshalom was commenting that the HN headline implies the car does 96 mpg, whilst travelling at 100 mph. Which would be a truly remarkable feat.
- Avshalom 14y agoYes. And it's a good thing to keep in mind with talk about self driving cars and 100mph HOV lanes on HN recently.
- reitzensteinm 14y agoBut you don't need the lanes to go 100mph - during the morning traffic jams, they could just go 100kph (or ~60mph), taking a tenth the time and half the normal fuel consumption of a commute. Once that happens, you can be damn sure that every new car purchase by someone that commutes will have the system. So while you may be right that 100mph lanes aren't a good idea, the idea has a lot of merit.
- qq66 14y agoWith self-driving cars you can safely keep traffic bumper-to-bumper which reduces aerodynamic drag significantly. Self-driving 100mph HOV lanes could very easily be more efficient than human-driven 70mph lanes.
- planetguy 14y agoI dunno, actually. Given that cruising is very efficient compared to stopping and starting, I think if you decided to optimize for fuel economy at exactly 100mph you could probably squeeze that kind of fuel economy out of a car. Optimize for aerodynamics, give it a tiny cross section (I'm thinking passenger behind driver), lowest rolling resistance tires you can manage, and put in a small engine and a super-long gearbox so that your engine is turning at maximimal efficiency when the car's doing 100mph. I don't think it'd be that difficult. On the downside it would of course be tiny and have terrible acceleration. Or, to put it another way, my big heavy car gets nearly 30mpg when cruising at 100mph, so all you really gotta do is reduce drag.
- teamonkey 14y agoIt's perfectly accurate if you're British.
