The two-seat drop-top has been shown alongside a facelift for the i8 Coupe; both models share almost everything from the 374hp hybrid powertrain and new design to the interiors and features.
Inside there are a few changes other than the loss of the two rear seats - you get a new 8.8-inch touchscreen display, upgraded steering wheel and instrument panel as well as some other tweaks to the dashboard. The roof can open or close in 16 seconds and do so at speeds of up to 49km/h. The further optimised BMW eDrive technology employed in both models comprises a high-voltage battery with significantly expanded cell capacity and energy content, and an electric motor generating a higher peak output. The key ingredient is a new lithium-ion battery pack developed specifically for the i8 thanks to BMW's practice with the array of plug-ins the company has produced since the i8's introduction.
Lastly, BMW has also confirmed the i8 Roadster will have a slightly different suspension/steering tune, the Munich-based manufacturer telling us this allows the Roadster to retain the trademark handling and performance qualities.
The BMW i8 Roadster has finally arrived, alongside an updated i8 coupe.
The i8 Roadster includes a power-retractable cloth panel over the cabin that stows away in 16 seconds, and can be operated at speeds up to 31 miles per hour.
The i series vehicles has been BMW's electrified brand on the road since 2014.
The petrol engine churns out the same 228bhp it did to drive the back wheels, but the electric motor for the front wheels gets an extra 12bhp (that'll transform it) for a total of 141bhp. The electric motor is good for 105kW and pure EV range is quoted at 28km.
The new BMW i8 makes a run to 100km/h in 4.4 seconds, though BMW admits the Roadster is two tenths slower. Both cars can reach a top speed of 155mph. Exclusive 20 inch wheel designs are also available, weighing 2.2 lbs less than the previous BMW i8.
Several adaptations had to be made, however, including the use of newly designed frameless gullwing doors made from CFRP with an aluminum outer shell, as well as the windscreen frame made entirely from CFRP.
Both can be ordered with Tera World Copper interior trim, which is new to the i8, and features a cloth and leather upholstery combination in a two-tone (Amido/E-Copper) colour scheme.More news: Virat Kohli's appetite for runs is unparalleled, scores fifth Test double ton
