2019 BMW i8: larger battery, more range, and new Roadster

BMW is breathing some fresh air into its three-year-old alternative flagship to improve performance, increase range, and add some style.

Revealed at the 2017 Los Angeles Auto Show, the i8's mid-cycle refresh increases its battery capacity from 7.1 kwh to 11.7 kwh, improving the car's fairly paltry all-electric range from 15 to 18 miles.

But if you're buying the i8 for its EV-mode range, you're missing the point.

Instead, the more robust battery exists to power an electric motor now throwing down 141 horsepower, a jump of 12 hp over the previous motor.

The new electric motor is still paired with a 1.5-liter turbocharged inline-3 ICE, which has been tweaked to reduce noise.

The combined system now produces a net 369 horsepower, up from 362.

However, the i8's drivetrain upgrades aren't the biggest news for BMW's alt-powertain i brand; the new 2009 BMW i8 Roadster is stealing the show in Tinseltown.

The production convertible arrives five years after the debut of the i8 Concept Spyder. It loses its rear seats and gains 132 pounds of heft over the coupe in the process.

Aside from its powered soft-top and lack of rear thrones, the i8 Roadster sports frameless doors, a vertical rear window, a new engine cover, and new aerodynamic cowls to better channel air to the Roadster's rear spoiler winglets.

BMW quotes a 16-second transformation time for the Roadster's soft-top, which can be raised and lowered at speeds of up to 31 mph.

Additionally, the i8 Roadster receives a raft of changes beneath its skin to ensure performance is on par with the coupe.

Engineers gifted the convertible with a bespoke suspension and damping tune, modified its steering characteristics, firmed up its roll stabilization, and made steering more precise.

Combined with the i8's upgraded drivetrain, the Roadster sprints to 60 mph in 4.4 seconds. Coupe models achieve the feat a mere 0.2 seconds quicker.

The 2019 BMW i8 reaches showrooms next spring. Pricing information will be announced closer to the market launch.
