BRASH EXTERIOR, FAMILIAR INTERIOR

Critics who sized up the production i8 Coupe years ago concluded the car’s wild exterior styling would age terribly. They were wrong.

Effectively unchanged for the 2019 model year, the i8’s bodywork remains compelling, with complex shapes, sharp angles, and fluid curves. A low, pointed nose, piercing LED headlight and taillight signatures, a floating roofline, and a layered rear end make the i8 instantly identifiable among more conservative sports cars. The topless model’s fabric roof, unique 20-inch wheels, and Roadster badging on the C-pillars pique the wow-factor.

Tera World Copper editions, like our tester, can be configured with burnt orange paint and include gloss black brake calipers. One peculiarity to the i8’s appearance is its partial-closing door windows. Neither coupe nor convertible versions allow passengers to completely lower the glass, making it awkward to rest an arm on the doorsill.

Inside, BMW attempts to keep the exterior’s futuristic look flowing with blue ambient lighting, a thin white border on the steering wheel, and a curved dash, but it’s near impossible to overlook the classic German cabin layout. The center stack is particularly puzzling, with an ordinary arrangement of buttons and a tall gear selector pulled straight from a 2 Series. Material quality matches the brand’s other products, heated, leather-wrapped seats are handsome and comfortable, and dihedral doors are unquestionably cool, but we long for something more luxurious or tantalizing from the automaker’s aspirational model.

One would expect to find suitably futuristic technology, but the i8’s convenience and safety features are merely contemporary.

By far the most frustrating aspect of the i8’s interior is the struggle to access it. A high, deep sill and protruding A-pillar force driver and passenger to contort their bodies to plop into the cabin. Even with the roof stowed, entry and exit is a challenge. Comparatively, other low-slung supercars like the Audi R8 and McLaren 570S provide large cutouts to place a foot in the cabin and stabilize entry. Storage space is truly tight as well, with a small cubby (4.7 cubic feet) within the i8 Roadster’s rear hatch and a rectangular hold (3.5 cu. ft.) where the i8 Coupe’s rear seats typically reside. If it’s practicality you’re after, few high-end sports cars do it better than the McLaren 570GT. You’ll pay more for it than for the i8, though.

CONSERVATIVE TECH

One would expect to find suitably futuristic technology within such a forward-looking design, yet the i8’s convenience and safety features are merely contemporary. The rosier side of that, however, is that everything is easy to operate and quick to access.

Protruding from the top of the dashboard is an 8.8-inch touchscreen display running BMW’s iDrive software. The tiled layout compartmentalizes key entertainment, navigation, and telemetry information. Opening one of these tiles reveals more settings and details; a split-screen mode allows the user to quick-select settings on part of the screen. A few shortcut buttons accompany a touch-sensitive controller mounted on the center console. Display resolution is excellent and the system responds to inputs immediately.

Apple CarPlay is included as standard, but after the first 12 months, the smartphone integration tool becomes subscription-based at $80 per year. Not only do sub-$30K cars include this resource for free, but the fact that BMW’s halo model doesn’t come with CarPlay for the life of the vehicle is truly disappointing. Android Auto, meanwhile, isn’t available at all. Other missteps include a single USB port hidden within a small console cubby, no Wi-Fi hotspot, and no wireless phone charging.

The i8’s 27-combined mpg means we barely drained half of the 11-gallon tank after a week’s worth of mixed driving.

Driver assistance tech is equally underwhelming, with only automatic emergency braking, parking sensors, and a surround-view camera system on offer. A digital gauge cluster, Harmon Kardon sound system, dual-zone auto climate control, and heated seats are the few convenience highlights.

DRAMA-FREE MOTORING

People shop the high performance vehicle segment for more than the terror of taking a highway onramp a bit too quick. Some desire the look and feel of a sports car with the road manners of a luxury commuter. And while potent coupes are easier to drive today than ever before, few are as accessible as the BMW i8.

Rather than wielding a raucous eight-, 10-, or 12-cylinder engine, the i8 Roadster uses just three cylinders of forced induction fury to motivate its rear wheels. The remainder of the car’s power comes from an 11.6-kWh battery pack and two electric motors turning the front wheels. Combined, the i8 serves up 369 horsepower and 420 pound-feet of torque through a six-speed automatic gearbox (the electric motors run through a two-speed unit). The 12-hp bump in output compared to the old i8 doesn’t affect the car’s 4.4-second sprint to 60 mph or 155-mph top speed.

Four drive modes manipulate the i8 Roadster’s performance and efficiency. By default, comfort mode taps both electric and gas powertrains to smoothly propel the vehicle without great urgency. Those hoping to maximize their fuel economy can select Eco Pro, which slackens throttle response, turns off air conditioning, and sends the car into its highest gear as quickly as possible. Sport mode has the opposite effect, calling to task every bit of power the i8 can muster, holding gears, and recharging the lithium-ion battery.

Unlike even the hybridized NSX, the plug-in i8 also has a pure electric range. With three more miles than the outgoing model, the 2019 i8 Roadster offers 18 total miles of e-travel before the gas engine kicks in. Unlike some hybrids, the i8 will also run at considerable speeds (up to 75 mph) on electric power. Our experience behind the wheel made it clear those 18 miles disappear quickly, however – even in comfort mode. Still, the i8’s 27-combined mpg means we barely drained half of the 11-gallon tank after a week’s worth of mixed driving. That’s on par with a family-friendly crossover, and considerably better than any sports car in the i8’s price bracket.

As the only two-door, two-seater sports car with a plug-in hybrid powertrain, the i8 is certainly unique.

Scooting around town and coasting along highways, the i8 is effortless to drive. The suspension is well damped, the steering is direct, and the powertrains change hands seamlessly. Sport mode is entertaining as well, with the electric motor providing off-the-line thrust and the gas engine building speeds from there. In corners, the i8’s rigid carbon fiber chassis keeps the car flat and stable, though road feel through the steering wheel is minimal. By no means can the i8’s driving experience be compared to a supercar, but it’s no snooze fest, either.

The i8’s one hiccup appears when drivers demand responsiveness from the car without giving it plenty of warning. When driving in comfort mode at low speeds, the sudden need for more power startles the i8, clunking the cabin as the gas engine engages.

COMPETITORS

As the only two-door, two-seater sports car with a plug-in hybrid powertrain, the i8 is certainly unique. Alas, the coupe’s $148,000 and roadster’s $163,000 starting figures put the two in competition with some serious performance vehicles.

If top-down motoring is your thing, you’ll no doubt be considering the Audi R8 Spyder ($177,100) and McLaren 570S Spider ($211,300). Though both cars carry higher price tags, they also have significantly more power. The R8’s 5.2-liter V10 is good for 532 hp and can propel the convertible to 60 mph in just 3.5 seconds. The 570S Spider, meanwhile, conjures 562 hp from its 3.8-liter, twin-turbo V8 and can sprint to 60 mph in just 3.1 seconds. All that power comes at a cost, however, with the 570S Spider averaging 18 mpg combined and the R8 Spyder managing an abysmal 14 mpg combined.
