BMW is out to rip up the sports car rulebook with its all-new i8.
Featuring jaw-dropping looks and advanced construction, the hi-tech newcomer promises to blend scorching supercar performance with supermini running costs. And its figures certainly make remarkable reading. With 357bhp the i8 is capable of sprinting from 0-60mph in under five seconds, yet it claims nearly 135mpg at the pumps, and boasts emissions of just 49g/km.
Facing the bold new BMW is one of the oldest sports cars on the planet: the Porsche 911. However, while the legendary rear-engined machine has been around for 50 years, the latest seventh-generation model is one of the most complete performance cars ever.
