What the BMW I12 Is

The BMW I12 is the chassis code for the i8, BMW's revolutionary plug-in hybrid sports car sold in the United States from 2014 to 2020. Developed under BMW's "i" sub-brand alongside the i3 city car, the i8 paired a lightweight carbon-fiber-reinforced plastic (CFRP) passenger cell with an aluminum drivetrain platform. The result was a low-slung 2+2 grand tourer that looked like a concept car made real, complete with dihedral scissor doors and a coefficient of drag among the lowest of any production sports car of its era. It stands as one of the boldest engineering statements in BMW's DNA, proving that efficiency and driving excitement could coexist.

The Models & Body Styles

The I12 generation was offered in the U.S. as two closely related variants:

• i8 — the launch hybrid coupe
• i8 Coupe — the fixed-roof coupe designation

Every I12 shared the same core layout: a mid-mounted gasoline engine driving the rear wheels and an electric motor powering the front axle, giving the i8 an unusual through-the-road all-wheel-drive character. You can confirm any specific car's build details with our BMW VIN decoder.

Engines & Drivetrains

At the heart of the I12 sits a turbocharged 1.5-liter three-cylinder gasoline engine mounted amidships, working in concert with an electric motor and a lithium-ion battery pack. The combined powertrain delivered brisk acceleration while allowing short bursts of pure electric driving. The three-cylinder feeds the rear wheels through an automatic transmission, while the electric motor drives the fronts through a two-speed unit—an ingenious solution that made the modest displacement feel far more potent than the numbers suggested.

What It's Like to Own & Buy

Owning an I12 is unlike owning any conventional BMW sports car. The carbon-fiber tub resists corrosion and keeps weight low, and the drivetrain has proven durable. Prospective buyers should verify the health of the high-voltage battery, inspect the tires (which are expensive, low-rolling-resistance items), and confirm the charging system functions correctly.

Notable Strengths

• Exotic looks and dihedral doors that still turn heads
• CFRP construction for low weight and no rust
• Genuine hybrid efficiency with sports-car performance

Things to Watch

• Specialized service and parts require an experienced technician
• Battery condition is critical to resale value
• Tight rear seats and limited cargo space

Enthusiasts cross-shopping the era's grand tourers often compare the i8 against traditional V8 coupes like the E63 and E64 6 Series, or larger luxury flagships such as the E65 7 Series—each representing a very different vision of BMW performance.
