The resulting space between the roof box and the seats is around 3.5 square feet, while the rear cargo area can hold 4.7 square feet of your BMW i8 cargo area-shaped objects.
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 2019 BMW i8 Coupe and Roadster feature multiple driving modes that include Comfort, Sport, and Eco Pro that adjust how the vehicle drives and feels.
Going into more detail, the aluminium parts of the hood have been made using 3D printing, in order to obtain greater precision, while BMW claims to have worked thoroughly on the insulation - both thermal and acoustic. In electric-only mode, the top speed is 120km/h, while the driving range is now up to 53km in the soft-top, and 55km in the coupe.
BMW has also had a fiddle with the glasshouse, beefing up the windscreen and quarter window and turning the rear window in to a deflector which can be raised or lowered wherever you have the roof. With an updated battery system, the hybrids now make 374 horsepower, up from the old i8's 357 hp.
Like the Coupe, the Roadster has gullwing doors, and the pair are available with new exterior paint finishes and 20-inch alloy wheel designs in either two-tone or black. The automaker claims the number of driving situations where the electric motor is exclusively responsible for powering the auto has been significantly increased, with the combustion engine only being brought into play when accelerating hard.
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 engine remains the same award-winning three-cylinder, turbocharged 1.5-liter, producing 228 horsepower (170 kW) and 236 lb-ft (320 Nm) of torque.
The roof is stored where the rear seats used to be but the Roadster still has storage around the roof box and its boot is bigger than the Coupe's.
Electric-only range is up to 18 miles - a gain of 3 miles. Top speed is limited to 250 km/h (155 mph).
Pricing has not been announced, but a BMW representative told us the i8 Roadster will start "north of $150,000".
It sure looks tempting in this new hue, called E-Copper.
