The Car Connection Expert Review

The 2016 BMW i8 blends a stunning coupe design with a slew of advanced technology underneath; the plug-in hybrid powertrain, and its corresponding efficiency, may be all but irrelevant.

The 2016 BMW i8 attracts attention for its exterior looks, but the technical wizardry in the plug-in hybrid powertrain should turn heads just the same. It could be powered by coal and ground-up baby seals and it'd still be viewed with awe and admiration by crowds gathered around to watch its "bird wing" side doors pivot up and out of the way. Nearly anyone feels like a celebrity when they're behind the wheel of an i8.

The i8's running gear is truly unique. When was the last time a stunning two-door came with a charge cord to plug it into a wall outlet? And a three-cylinder engine? The classic design cues are merely there to point out that it's possible to blend energy efficiency with both style and performance. And that makes the i8 a car unlike any other.

Its mission is to respond to what BMW says is the desire to enter "a new era of sustainable performance." And its highest-tech features may be its construction, with a body shell made of carbon-fiber reinforced plastic that attaches to an aluminum chassis that absorbs crash energy and carries the powertrain. Then there's the battery pack, the electric motor, and the three-cylinder engine too.

Review continues below

As a design, the i8 includes a number of elements of "normal" BMWs, including twin-kidney grilles at the front. But much of its style is owed to elements that are unique to the BMW "i" sub-brand. These include startling wing-like fins at the rear, blue trim accents, and a groove between the upper and lower rear bodywork. Like the i3, its smaller city-car counterpart in the "i" lineup, the i8 has unusually tall wheels and tires (20-inch wheels are standard) to reduce aerodynamic drag.

The interior is a blend of ultra-modern lines with some recognizable BMW bits from other cars. But they're executed in unusual materials that include reclaimed wood veneers and fabrics with recycled fibers. Both front passengers sit low, with a floating pod of instruments in front of the driver; the tall tunnel for the i8's battery pack forms a large divider. In our testing, we've been impressed with the highly contoured and ultra lightweight seats, although we've not yet taken an i8 on an extended drive to see if that holds true over longer distances.

Then there's the powertrain, really a pair of separate power sources, one per axle. At the rear, a high-output turbocharged 3-cylinder gas engine powers both rear wheels, while an electric motor motivates the front pair, fed by the liquid-cooled lithium-ion battery pack that boasts a usable energy capacity of around 5 kilowatt-hours. Because it's located between the seats, the entire car maintains a low, sleek profile.

The combination of engine and motor provide the i8 with split personalities: it can run only on electricity, as a zippy hybrid, or with both powertrains teamed together as a genuine sports car. It is a "through-the-road" hybrid; each propulsion mode is linked together via software, but they're not mechanically connected even whten they are working together.

The i8 was the first BMW to use the company's latest 1.5-liter turbo 3-cylinder engine, rated at 228 horsepower and 236 pound-feet of torque, powering the rear wheels through a 6-speed automatic transmission. The same engine is now found in a lower state of tune in the latest Mini Cooper line. The electric motor up front is rated at 96 kilowatts (131 hp) and 184 lb-ft of torque; it's used for electric-only driving at speeds up to 75 mph.

The electric range of the i8 is rated at 15 miles by the EPA, though BMW says the Max E-Mode setting can give up to 22 miles. The motor also offers a sort of power boost to complement the engine torque, when the car is running in "Sport" mode. In addition to three driving modes—Max E-Mode, Comfort, and Sport—the first two can be driven using the EcoPro function, which increase efficiency and range by capping acceleration and other energy uses. The default Comfort mode uses each powertrain or both in a more efficient manner, running essentially as a hybrid once the battery is depleted.

The EPA rates the i8's total combined range between the gas tank and a fully charged battery at 330 miles. And it gives the coupe a rating of 76 MPGe when running electrically. (MPGe, or miles per gallon equivalent, measures the distance a car can travel on the amount of energy contained in one gallon of gasoline.) When running as a gasoline hybrid, the BMW i8 gets a fuel efficiency rating of 28 mpg—decent for a high-performance sport coupe.

The BMW i8 starts at more than $140,000, putting it into a rarefied sector of pricey two-seat performance cars. Options can add another $10,000 or more, depending on how heavy-handed the buyer is on the specifications sheet. For 2016, BMW has received federal approval to offer the world's first laser headlights as an optional replacement for the standard LED headlights. They're stunningly good, giving as close to a daylight spread of distance vision as we've ever seen in a car.

It's entirely unclear whether more than a handful of six-figures sport coupe buyers care about reducing fuel consumption and sustainability. The innovative materials, advanced tech, and light weight of the BMW i8 have already made it a high-tech icon. It's more of a sports car that's comfortable as a touring car than an all-out track racer. Which is not to say that BMW isn't considering higher-performance models down the road. Meanwhile, we anticipate that the company will have no problem selling every one they build.
