What about the 1/4 mile? 12.3 @ 114 or just quicker than a stock E92 M3. Based on the figures it looks likes an i8 off the line would beat the previous generation M3 from a stop and the race from a roll would likely favor the M3 as speeds rise.
The curb weight is a relatively lightweight 3380 pounds. Another way to look at the weight is that the car is lighter than new F80 M3. Weight distribution is a very nice 48.5% front to 51.5% rear.
The car performs as expected and considering the 1.5 liter turbo three-cylinder with only 231 horsepower and the rest of the output coming from two electric motors good for a total of 357 horsepower it is quite efficient. Less power than an E92 M3, but just as fast. 420 lb-ft of torque certainly doesn't hurt.
It makes you wonder how good this car would be if they just gave it the N20 four-cylinder instead for some serious punch at this $135k price level.
