BMW i8 Instrument Tested - Real World Performance Numbers
BIMMERPOST NEWS BMW i8 Instrument Tested - Real Life Performance Numbers Can the BMW i8 drift? Seems we'll be seeing that answered soon by a Chris Harris review on Road & Track, but for now here are some real life performance figures from their instrumented test of the i8. The i8 (in hybrid mode) is able to cover 0-60mph in 3.8 seconds, quarter mile in 12.3 seconds @ 114.4 MPH. It hit 0.91g on the skidpad and braked from 60-0 in 119 feet. Via Road & Track Also see: 10 things we learned about the new BMW i8 (by Jason Cammisa at R&T). |

Dude... awesome. I've never seen one of these, really cool of R&T to post it up!
My thoughts so far, - Braking distance is a bit disappointing for such a [relatively] light car, though. - After 145mph it's "wind power"? - Their 0-60mph time is impressive though at 3.8s. - I wonder why the 5-60 is so much slower, has to be software related. Really looking forward to what Chris Harris has to say. Last edited by ddk632; 04-28-2014 at 10:45 AM.. |

0-60mph in 3.8??? Wow Very impressive!!! The braking distance from 60-0 is a bit worrying though. Overall very impressive numbers!!!

As expected for a heavily electrified vehicle it poops out above 80mph or so. Quicker than an E9x M3 through the 1/4 but considerably slower 60-130
Good it at least doesn't embarrass itself on paper against a 911. Most owners of either will never get close to the handling limits and the low grip of the i8 might even make it more fun for the average schlub

The numbers go hand-in-hand with the specs. The low curb weight coupled with the immediate torque will lead to some quick acceleration times in the low to mid range. Braking distances are essentially a product of mechanical grip. This is making due with what it's wearing.

Hopefully. All BMW's stop like hell so why would the i8 be any different?

Yeah tires and they said initial bite isn't very strong (in the notes on the sheet). Surely there's room for improvement. Hell, my 5300+ lb X6M does 60-0 braking distance in 107'.

I was curious if the extensive braking regeneration had any effect on the stopping distance...

Seems to stack up favorably against Tesla Model S. Of course it isn't a full 4 seater sedan. Pretty impressive times to 60 and will feel quite spirited it seems for daily driving

Thx Jason! That's some good news!
Under "TEST NOTES No2" they (R&T) write: "Initial brake bite relatively slow - might explain fairly average braking distance." IMO that means there's some EV regeneration interference with braking. Narrow tires and mass alone can't explain such high braking distances especially knowing there's issues with initial brake bite. Initial bite usually occurs at relatively high speed when brake power and in this case a good EV regeneration/brakes integration management are more important than tire/surface friction.

It really comes down to weight and tires. Most brakes have the ability to lock up tires under hat braking, so it really comes down to how well the car can manage what it's given. In this case, it's working with four relatively small contact patches. I don't know the ins and outs of how suspension geometry and ABS tuning plays into it, but the aim is to balance those four patches to eke out as much available grip as possible.

Didn't know it was AWD until now. But it makes sense since the 918 (et al) applies a similar concept, electric motor for the front wheels, internal combustion for the rear.
The times are very respectable, especially the 0-60. Part of me still wishes BMW AG would let BMW M touch this chassis and give it a full on M treatment & a gas guzzling, fire spitting, tarmac ripping Sxx motor. But this is becoming more and more promising, particularly when one realizes this [hybrid sports car concept] will be more common practice in the future & BMW just took a huge leap forward with a head start, especially at this price point. Great read & I'm optimistic about the i8, despite some of its shortcomings & cheesy gadgets (active sound).

braking sucks because it rides on low rolling resistance tires that are very thin. It stops about the same as most "normal" cars. I know that's not quite good enough for the demographic of buyers here, but it's not horrible is my point.

True, braking distance is "average" not "horrible". It's one of those things when you drive, you learn the car's limits, and make sure not to exceed them.

Will this Chris Harris' first authorship at R&T? Anyone know if he's becoming part of their editorial staff?
