Super cars going electric and are no less ferocious

The appeal of a supercar used to be relatively straightforward: aggressive styling, a growling engine, and racetrack-ready handling, garnished with an exotic name.

The time-honoured formula is being tested as customers demand more than just acceleration and a gawking public.

Supercars are starting to feature wireless connectivity, electric-engine options, and even apps to open the doors. Take Bugatti’s latest monster, the Chiron: It comes with an infotainment system that fades to invisibility on the cockpit screens as the car’s speed increases, specs that were absent from its predecessor, the Veyron.
