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

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.

The new BMW i8 Safety Car is the world’s first vehicle equipped for inductive charging with 7.2 kilowatts of power using Qualcomm Halo™ prototype technology . This allows the high-voltage battery of the BMW i8 to be fully recharged in around one hour only.

• Range on electric power only (EU): up to 37 kilometres (23 miles)
• Overall range: over 600 kilometres (373 miles)
• System output of FIA Formula E Safety Car: approx. 380 hp
• Maximum system torque: > 570 Nm (420 lb-ft)
• Top speed: 250 km/h / 155 mph (using electric power only: 120 km/h / 75 mph)
• 0 – 100 km/h (62 mph): < 4.4 seconds; 80 – 120 km/h (50 – 75 mph): 2.6 seconds

Modifications to comply with FIA Formula E requirements:

• Certified safety cell – bolted and bonded to load-bearing elements of the body. Use of patented tube joints.
• New bank of LED lights and stroboscope light
• FIA radio equipment and transponder integrated into the vehicle electronics
• 2 x additional 12V sockets with 25A fuse
• Carbon-fibre racing seats
• Carbon-fibre centre console
• Six-point safety belt
• Removal of interior trim and airbags
• Modified trim elements on safety cell
• Modified position of safety belts
• Official decals
