Finally a concept car that can be bought at decent price……BMW i8 – The Hyper Hybrid !!!
The Good Concept-car looks help the 2015 BMW i8 stand out in the crowd and a carbon fiber body keeps weight down. The plug-in hybrid drivetrain allows 22 miles of electric range and total output reaches 357 horsepower.
The Bad Skinny tires lack strong cornering grip and the hybrid drivetrain programming seems in need of refinement.
The Bottom Line The 2015 i8 commands a very high price, but it is the most exotic car currently bearing the BMW badge and offers a dual personality between efficient electric and powerful sport driving.
All you need to know:
The i8 is a sort of hyper-hybrid, what might have happened if Ferrari had developed the Prius. It exhibits two very distinct personalities: energy-obsessed engineer and troubled youth. Driving it in its Comfort and Eco Pro modes, I could have parked and forgotten all about it, but after moving the shifter to Sport mode nothing short of violence was going to get me out of the i8.
Hitting production in conjunction with the more affordable and mundane i3, the i8 represents BMW’s radical rethinking of personal transportation in light of climate change issues and shrinking fossil fuel supplies. The i8 seems like a first effort by BMW to bring in new century efficiency yet maintain its performance legacy, and it will cost you dearly.
Base price in the US comes to $135,700 before adding any of the available “World” trim levels. UK buyers are looking at £99,845, although the i8’s electric-only mode should avoid congestion charges and preserve the village green. Below the equator, Australians are looking at $299,000 for the i8.
The i8 is certainly an extraordinary-looking vehicle, as if BMW built a concept car then forgot to get rid of all the interesting bits before putting it into production.
Power front and back
Beyond its concept-car looks, the i8 uses a completely unique drivetrain, bearing no resemblance to even BMW’s own hybrid vehicles. Tucked away somewhere in the car is a turbocharged 1.5-liter three-cylinder engine using BMW’s valve timing and throttle control technologies to produce 228 horsepower and 236 pound-feet of torque, driving the rear wheels through a six-speed automatic transmission. That engine, a variant of that found in the 2015 Mini Cooper, gets a little help from the 11-horsepower starter motor, smoothing over turbo lag.
Driving the front wheels, the i8 uses a 129-horsepower electric motor, powerful enough to move the car all by itself when the 5 kilowatt-hour battery pack has enough charge. Oddly, a two-speed transmission sits between that motor and the front wheels. Filling the battery pack takes just 1.5 hours from a 240-volt source, and gives the i8 22 miles of zero-emission range.
BMW sets the total power output for the i8 at 357 horsepower and 420 pound-feet of torque, with a 0 to 60 mph time of 4.2 seconds. EPA figures show 76 miles per gallon equivalent, 28 mpg average on the gasoline engine alone. However, as is typical with plug-in hybrids, mileage will vary drastically depending on how frequently the car gets charged up.
Further setting it apart from the BMW line-up, the i8 makes use of carbon fiber for its passenger compartment and aluminum sub-assemblies for engine support and chassis. Unfinished carbon fiber was in evidence , a subtle means of calling out the i8’s use of this exotic material. That construction helps keep the weight down, but the i8 still tips the scales at a 3,455-pound curb weight.
A couple of simple latches in the cargo area let me gaze at the black metal box containing the battery pack, occupying a mid-body position in the car. A hatch on the left front fender covers a J1772 electric vehicle charging port, while a standard fuel filler sits at the right rear.
The i8 uses 2+2 seating, meaning there are padded spaces behind the rear seat where you could put your computer bag or possibly some groceries. A compartment under the rear hatch could have held a couple more grocery size bags.
Eco Pro, Comfort and Sport
Appropriately for a car from the future, the i8 lit up accent lighting and various screens around the cockpit, but no burst of combustion broke the quiet. In Comfort mode by default, the LCD instrument panel tinted its speedometer and power gauge blue. BMW’s usual rocker switch for drive modes, mounted on the console, only offered Comfort and Eco Pro modes, lacking the Sport and Sport Plus settings of other BMW models. A button labeled eDrive on the console promised to keep the i8 driving under electric power, if the battery would allow it, while the shifter had a pull-to-the-left Sport position.
BMW uses the navigation system to look at the road ahead, adjusting the drivetrain power output in advance of ascents.
When you consider the two power sources driving different sets of wheels and the two intervening gearboxes, BMW did a masterful job of making the i8 an exceptional driver. The car must match power front and rear, then decide which end needs more torque based on road and driving conditions. The fact that it all works so well can be chalked up as a big win for BMW engineers, and I hope to see the company capitalize on this technical achievement in other cars.
This example came with energy-saving LED headlights and a head-up display, projecting vehicle speed and route guidance on the windshield. A camera mounted at the top of the windshield enabled a pre-collision braking system, which also warns if it thought people do not brake soon enough to avoid hitting cars ahead. BMW offers a surround-view camera for the i8 to help keep its carbon-fiber body panels unscathed.
As I’ve seen in other BMW models, the i8’s cabin electronics are among the best available. Sitting up on the dashboard, BMW’s standard wide LCD shows navigation, stereo and online information, along with a few added screens detailing the car’s energy usage. BMW’s latest iDrive controller, with its embedded touchpad, let you control all on-screen features. Likewise, voice command was present, giving easy control over most infotainment system functions.
The excellent navigation system shows detailed maps with extensive traffic coverage, giving route guidance a better chance of keeping the i8 out of traffic jams. The navigation system’s points-of-interest database added a section for charging stations, appropriate for the i8. But when I checked the list it was oddly empty, not showing any of the many charging stations I know exist around San Francisco.
BMW offers a very good set of connected features, including online destination search and third-party apps. Some of these connect through the car’s built-in data connection, and some rely on the BMW ConnectedDrive app for smartphones. This app is fully functional for iPhone, but the recent Android version seems to lack many of its counterpart’s features. I have been extremely impressed by BMW’s online features in cars such as the M4, but none were working in this i8. BMW assures me that all of its connected features come standard in the i8, which I would expect for such a high-priced and futuristic car. In addition, the i8 gets a telematics system letting owners check the charge status from a smartphone app.
The i8’s own head unit showed me different charging options, such as the ability to take advantage of low-priced electricity in the earliest hours of the morning.
Audio sources ran the full gamut of what I’ve seen in other BMW models, from an onboard hard drive to HD radio. That music library interface, identical to that used for devices plugged into the car’s USB port and the onboard hard drive, still suffers from an over complicated design. It takes far too many button pushes to find and play music.
Music, and the engine note, plays through a Harman Kardon audio system built for the i8. Featuring 11 speakers and a 360 watt amp, you can enjoy listening to music in the car, although the quality may never rose to truly sharp audiophile levels.
The 2015 BMW i8 is an extraordinary technical achievement. Although pricey, it is near the cheapest car you can get with a full carbon fiber body. Its look is pure concept, and much more interesting than its sibling, the i3. Although I found some odd issues with its fuel economy, this plug-in hybrid system impressed me with its power control.
Most impressive was the i8’s Sport mode, which made for a surprisingly different ride. I’ve noted and appreciated the dual nature of previous BMW models, especially those bearing the M, but the i8’s personality split is so wide that it deserves two model names.
BMW hasn’t played up its connected car features much, but they are impressive, as is its cabin tech. The i8 comes with the latest iDrive system, featuring excellently detailed maps and very functional voice command. The connected features, although not working on this example, make online destination search quick and easy. Integrated apps offer online music and safe social media status updates.
If the i8 represents BMW’s future, the company is already years beyond the competition.
