These numbers mean that while Elon Musk's new Tesla Roadster can promise a 0-60 run in 1.9 seconds, the i8 family remains on the conservative side with a time of 4.2 seconds for the Coupe, and 4.4 for the Roadster. Also included is new technology such as BMW's controversial "display key" as well as the latest iDrive infotainment system.
Under the hood of the 2019 all-wheel drive i8s are two electric motors and a three-cylinder turbocharged engine.
The Roadster's soft-top is all-electric and opens in 15 seconds at a button's push while traveling up to 31 miles per hour. When retracted, the soft-top folds into a compact package and stows away in a perpendicular position, creating around 100 liters of storage space behind the seats.
Combined maximum power increases to 374bhp, while electric-only mode manages just under 20 miles of range up to a maximum speed of around 70mph. Opening the roof raises the rear window automatically by around 1.9 inches, but the driver can also adjust the height at the touch of a button.
The result is more power with the gross energy rating now up 7.1kWh to 11.6kWh giving the electric motor which drives the front wheels a power output of 143 horsepower. The automaker claims the number of driving situations where the electric motor is exclusively responsible for powering the vehicle has been significantly increased, with the combustion engine only being brought into play when accelerating hard.
Roadster Arrives With Refreshed BMW i8 Coupe
Sales of the BMW i8 Roadster are set to commence in spring 2018 with pricing announcements closer to the market launch.
What the i8 Roadster does offer over the coupe in performance is range.
The Roadster gains 60kg over the coupe, mainly on account of the reworked chassis that allows for the folding roof.
Other than two new colors (E-Copper and Donnington Grey) and a badge behind the doors, the Coupe looks pretty much like its predecessor. And like the coupe, the i8 Roadster boasts upward-swinging "gullwing" doors that further emphasize this a sports auto as not just another innovative vehicle, but rather art on wheels.
Both cars are powered by a reworked version of the previous petrol-electric hybrid system. Mpg has also been improved to 149.8mpg for the Coupe and 134.5mpg for the Roadster, although these numbers are always notoriously hard to replicate in the real world, unless you charge frequently and mainly undertake short journeys.
