BMW i8 gets Performance Upgrade for Motorsport – as Safety Car at Formula E

This is the first BMW i8 build only for one purpose: The rule the race track! Get all the information about the performance prototyp of the new BMW i8 as Official FIA Formula E Qualcomm Safety Car.

When we interviewed Henrik Wenders, product manager for BMW i, back in 2013, he stated: “The BMW i8 is not built for the race track”. And since this is still appropriate for the normal BMW i8, there is one special prototype out there – with just the right equipment, actually beeing build for the race track!

The BMW i8 will continue as the Official FIA Formula E Qualcomm Safety Car through the second season of Formula E. The modifications to the two new Safety Cars are far more performance-oriented and they have been adapted to meet the FIA’s technical regulations ahead of the new season, which gets underway in Beijing on 17 October.
