This is the car that people in the 1970s predicted we would be driving in the year 2000. Fifteen years after the turn of the millennium, the BMW i8 is the machine that looks like no other BMW — and certainly like no other car on the road. Its gasoline and plug-in electric powertrain compliment its looks, bringing together the efficiency of an electric car and the convenience of an internal combustion engine.
But there is a lot more to understand about what the BMW i8 is and is not. Is it an exotic supercar? Or is it a dream of the environmentally minded automotive enthusiast? Or is it something else altogether? Could this be the one vehicle which we cannot currently classify? Or is it all of these things?
Has the future finally arrived?
Its looks alone draw the attention of everyone on the road. Pedestrians gawk. Other drivers wave or even honk. Some yell out compliments. When parked, crowds gather, pictures are taken. Bros shower it with awe. Ten-year-old boys spew out its specs. Everyone asks to open the doors. Women seem more reserved, quietly judging the car and then its driver. (Except that one mid-twenties woman who, after a quick conversation that divulged her knowledge of all things cars, ditched her man, jumped into the passenger seat, and was ready to go wherever I was going.) Two Jamaican guys explained to me that BMW really means Bob Marley and the Wailers. Most people had no idea what it is but they knew it was special. Potential i8 buyers should know that all this attention gets old really quickly.
Pop up the door, place your butt on the wide door sill and slide into the seat — practice makes you a superhero. Once inside, the interior seems intimidating at first, but within a few minutes similarities to any modern BMW can be seen. In fact, I have not noticed any features in this car that can’t be had on a common yuppie enthusiast-leased 335i. Visibility is shockingly good for a mid-engine car. There are small jump seats in the back, which my seven year old daughter loved as she could see out and no one could see her. Much like the Audi R8 or the Acura NSX, and unlike any Ferrari, everything about using this car as a car is shockingly normal and drama free.
In the middle of this vehicle is a three cylinder, 1.5-liter turbocharged engine that produces 228 horsepower while inhaling air at 22 psi. Next to it is a tiny electric motor that produces eleven horsepower and is used mostly to start the engine and mask the turbo lag. It can be thought of as an electric supercharger. Those two send the power to the rear wheels via a six-speed automatic transmission. Up front is another electric motor that produces 129 horsepower and sends its power to the front wheels via a two-speed transmission. Combined, this gadgetry produces 357 horsepower, which sure as heck does not seem like a lot for a mid-engined exotic in the days of 707-horsepower family sedans.
It is my suspicion, however, that BMW wants you to think of its powerplant as a black box. The front clam-shell cannot be opened by anyone other a factory trained technician. The rear engine can be accessed through the rear hatch, except it really can’t. Underneath what looks like an engine cover is another engine cover which is secured with Allen bolts. I cannot recall any other vehicle in which the engine was completely sealed off. Even the 911 allows you to see part of the intake manifold.
Instead, BMW wants you to focus on are the three main driving modes: eDrive, also known as electric; Comfort, also known as normal; and Sport, also known as faster than Comfort. In eDrive, the i8 is a front-wheel-drive electric car. In Comfort, it’s an all-wheel-drive car with either the gasoline engine and/or the electric motors propelling the vehicle forward. In Sport mode, the three-banger is working full-time, the front transmission shifts into another gear, and the rear transmission stays in gear longer. All of this is accompanied by a concert of noises never heard from one car before; the i8 quietly whistles, whines, and snorts, all at the same time.
The EPA rates the i8 for 28 mpg in the city and 29 mpg on the highway, for a combined 28 mpg rating. That may not sound impressive because it does not take into account the 76 eMPG rating, which is the distance a vehicle can travel in electric mode using the amount of energy contained in one gallon of gasoline. The i8 can travel up to fifteen miles in eDrive with a fully charged battery, but that is where I ran into a problem.
I live in a downtown Boston high-rise building where each parking spot is privately owned. There are no changing stations or outlets available, so I was not able to charge the car there. Yes, there are charging stations, but they required me to either park on a downtown street — which I never do with press cars — or pay an exuberant amount of money for a night of parking a mile from my home. Neither of these was a viable option for me, so I relied on the battery being charged through regenerative braking and the three-banger. My driving was limited to heavy city traffic or sensible hooning, nothing in between. My result was a computer-indicated 27.4 mpg, which I thought was pretty good given the circumstances. If I had access to a charging station, I would have no issue driving to work and back in purely electric mode.
The i8 is made of a plastic-reinforced carbon fiber tub which sits atop an aluminum alloy frame, with some magnesium thrown in here and there. There are parts of the body that were intentionally left unfinished or unpainted, which look like a mix of fiberglass and carbon-fiber. The batteries, which are located in what could be described as the transmission/driveshaft tunnel on a typical car, along with the motors, are the heavy parts. The curb weight of the i8 is 3,455 pounds, the bulk of which is located just a few inches from the ground.
On paper, with 357 horsepower and at 3,455 pounds, the BMW i8 does not seem all that impressive. Yet, in street driving, it’s like nothing else I have ever driven, mostly due to the massive amount of torque that is instantly available. The total sum of torque the i8’s black box, derived by some highly complex formulae, is 420 lb-ft at some irrelevant engine speed. This is what the driver and passenger feel and it’s what gives the i8 the sense of fast. Be it from the electric, conventional, or both motors, the power is always there; there are no dead spots, no waiting for boost to build, no ridiculously high redlines. Quietly and smoothly, pinning its occupants to their seats, the BMW i8 just goes.
In a sense, that is where the i8 does not make any sense. The common metrics we associate with performance do not relate the same way to the i8. On paper, the i8 may not be faster than a Porsche 911, but is sure as heck feels faster. Neither any hybrid, nor any vehicle with a three-cylinder engine, is supposed to be this fast. It’s worth noting the obvious: In addition to being fast, the i8 is very much a driver’s car. Handling and feedback through the chassis is typical of sporty BMWs, that is to say great and on par with the Audi R8.
One may think that the i8 is the new M1, but it isn’t. A quick glance inside will reveal that it’s not an M car at all. The seats are not as supportive and lack the various adjustments of the amazing seats that come in every BMW M car. There is no M anything; no M modes, no M buttons. Even the tires, while perfectly suited for the street, and not at all objectionable in casual hooning, aren’t worthy of a crapcan racer (note: this vehicle had the sportier 215mm and 245mm wide tires). The i8 is fast, it does everything well, but it’s not something anyone would do a track day in, and therefore it is not an M car.
What the i8 shares with the iconic M1 is that both vehicles mark the start of new era for the BMW brand. The M1 started a line of fantastic performance, yet functional, vehicles. The i8 is here to prove that electric and efficient does not mean boring and slow. None of that stuff about the engine, the motors, the batteries, and the power distribution matters. Here is a machine from the future and in it is a black box that makes it go. It’s stunning, it’s fast, and it’s green.
The future is now.

- BklynPete So let's get this straight: Ford hyped up the Bronco for 3 years, yet couldn't launch it to match the crazy initial demand. They released it with numerous QC issues, made hay for its greedy dealers, and burned customers in the process. After all that, they lose money on warranties. The vehicles turn out to be a worse ownership experience than the Jeep Wrangler, which hasn't been a paragon of reliability for 50 years. The same was true of the Aviator, Explorer, several F-150 variants, and other recent product launches. The Maverick is the only thing they got right. Yet this company that's been at it for 120 years. Just Brilliant. Jim Farley's non-PR speak: "You don't get to call me an idiot. I get to call myself an idiot first."Farley truly seems hapless, like the characters his late cousin played. Bill Ford is a nice guy but more than a bit slow on the uptake too. They have not had anything resembling a quality CEO since Alan Mulally turned the keys over to Mark Fields - the mulleted glamor boy who got canned after 3 years when the PowerShi(f)t transaxles exploded. He more recently helped run Hertz into the ground with bad QC and a faulty database that had them arresting customers. Ford is starting to resemble Chrysler in the mid-Seventies Sales Bank era. Well, at least VW has cash and envies Ford's distribution reach and potential profitability.
- Mike Beranek This guy called and wants his business model back.
- SCE to AUX The solid state battery is vaporware.As for software-limited pack capacity: Batteries are obviously the most expensive component of an EV, so on the rare occasion that pack capacity is dramatically limited (as in your 6-year-old example), it's because economies of scale briefly made sense at the time.Mfrs are not in the habit of overbuilding pack capacity just for fun, and then charging the customer less.Since then, pack capacities have been slightly increased via software because the mfr decides they can sacrifice a little bit of the normal safety/wear margin in the interest of range. We're talking single-digit percentages, not the 60/75 kWh jump in your example.Every pack has maybe 10% margin built into it, so eating into that today (via range increases) means it's not available to make up for battery degradation tomorrow. My 4-year-old EV still has its original range(s) and 100% SOH, but that's surely because it is slowly consuming the margin built into the pack.@Matt Posky: Not everything is a conspiracy to get your credit card account, and the lengthy editorial about this has nothing to do with solid state batteries.
- JLGOLDEN In order for this total newcomer to grab and hold attention in the US market, the products MUST be an exceptional value. Not many people will pay name-brand money for the pretty mystery. I can appreciate the ambition of selling $50K+ crossovers, but I think they will go farther with their $30K-$40K offerings.
- Dukeisduke They're where Tesla was when it started - a complete unknown. I haven't heard anything about a dealer network. How are they going to sell these? Direct like Tesla? Franchises picked up by existing new car dealers?
