i8 = $135,925. The SLS will be $550,000, the Porsche 918 will be $845,000.
The Audi e-tron (electric R8) won't even be built anymore.
What is important to take note of, the i8 makes 170kW and 320Nm from a 1.5 3-cyl, which is modular and can be used for other models. That's E46 330i power from a turbo 1.5 3-cyl that apparently sounds like a Porsche Carrera...
SLS: 4WD, 740bhp, 738lb ft, 0g/km CO2, 0-62mph in 3.9secs, 155mph, 155-mile range, 3hr fast charge, 2110kg
i8: 4WD, 362bhp, 420lb ft, 0g/km CO2, 0-62mph in 4.4secs, 155mph, 310-mile range, 1.5hr fast charge, 1490kg
The i8 has got it beat. So the SLS has all that extra power and torque and only does 0.5 of a second better to 100?
Plus, the SLS has been seen before, it's old hat, the i8 design is unlike anything else on the road, probably the only truly futuristic design on a production car at the moment
i8 FTW
