The actual stats look depressing. 105mph top speed, 0-60 in 5.5 seconds, 20 minutes of racing before being drained... Doesn't the Tesla Model S beat this on pretty much everything except "looking like a 1940's race car"?
- shiftb 9y agoThe whole thing is made of steel instead of lighter weight materials. I'm sure that has some impact as well. It really is a beautiful car though.
- castis 9y agoThis probably says more about me than anything else but I dont think I've ever built a prototype of anything thats outperformed a production model product.
- henji76 9y agoI think a prototype should outperform production cars in at least one stat. Else what's the point ?
- bch 9y agoResearch and development
- Sir_Substance 9y agoScoping the problem, and looking for non-obvious traps that might sink the project.
- jdmichal 9y agoAgreed. I'm probably being a bit too picky about the language. I'd have a different response if this was "an electric car inspired by 1940's racers" [0], but was very disappointing when I thought I was reading about a "race car prototype". [0] I think it looks awesome, and they certainly did a great job with the aesthetics.
- sp332 9y agoThat's not bad for such skinny tires. Anyway it's a concept car, so making it drivable in any way was an afterthought.
- dsfyu404ed 9y agoA 90s pickup truck with the higher end engine option will barely beat it in top speed and blow it out of the water in endurance. This is a concept car and will likely see a lot of 20min runs on the track to determine if they want to do more testing of whatever it is they're testing here.
- silassales 9y agoTesla Model S: 0-60: 2.8 sec Top Speed: 155mph Range: 337 miles
- semi-extrinsic 9y agoThis has 20 minutes of racing time. That's about 4x more than a Model S will do before it overheats and goes into turtle mode.
- saulrh 9y agoSeems like modern top-line racing cars do 30-45 minutes between pit stops across formats and styles. 20 minutes is within a factor of two. For a prototype that's pretty solid, and I take it as a message that the technology is approaching parity.

- valesco 9y agoI'd look at Formula E if I wanted to see parity.
- jdmichal 9y agoIs that anything more than cooling? Obviously that huge grill on the prototype helps massively with that. I'm sure a Tesla that's not concerned with being a functional sedan could manage to dissipate enough heat to prevent that.
- semi-extrinsic 9y agoChoice of battery tech is a big one. Basically, you can do like Tesla and go with LiCoNiAlO2 to get the highest possible energy density, at the cost of higher internal resistance (i.e. dumping lots of current produces lots of heat). Or you can do like Formula-E cars (or RC helicopters, drones etc.) and go with LiFePO4 and sacrifice some range for the ability to dump massive amounts of current all the way to empty. Cooling is fine and dandy, but it's hard to make efficient cooling reach into the internals of batteries. Reducing heat buildup pays greater dividends.
- jdmichal 9y agoAh, got it. Though it only worsens my confusion over why they can't dump enough current to do better than 0-60 in 5.5 seconds... Do those other technologies also have lower current output overall due to the lower energy density?
- kylegordon 9y agoI am, as this very moment, timing a national level UK race meet, and none of the 13 events this morning has yet to go over 15 minutes. 20 minutes per race is more than enough to take part in regular national race meets here in the UK.
