2014 BMW i8 Coupe (I12) Dimensions, Size & Specs

The BMW i8 Coupe (I12) has a curb weight of 1485 kg (3275 lbs) and a maximum weight of 1855 kg (4089 lbs). The relatively lightweight construction, thanks to extensive use of carbon fiber-reinforced plastic and aluminum, enhances acceleration, handling, and efficiency, while the maximum weight accounts for passengers and cargo. This balance allows the i8 to deliver sporty performance without compromising on the hybrid powertrain's efficiency.

The BMW i8 Coupe (I12) offers 154 liters (about 5.4 cubic feet) of luggage capacity. This is on the smaller side compared to traditional sports cars and coupes due to the hybrid battery packaging and aerodynamic design constraints. While it's enough space for a couple of small bags or a set of golf clubs, it may not be ideal for larger luggage or extended trips, reflecting the i8's focus on performance and style over practicality.

The BMW i8 has a ground clearance of 117 mm (4.6 inches). This low ride height contributes to its sporty handling and improved aerodynamics but requires careful driving over speed bumps, steep driveways, and uneven roads. Owners may need to adopt cautious entry and exit maneuvers to prevent damage to the undercarriage or front splitter.

The BMW i8 Coupe (I12) comes equipped with rims sized 7.5J x 20 inches at the front and 7J x 20 inches at the rear, paired with tires sized 215/45 R20 on the front and 195/50 R20 on the rear. These wide, low-profile tires enhance grip and handling, complementing the vehicle’s sporty character and providing excellent road feedback.

Yes, the BMW i8 Coupe (I12) fits into a standard garage, but due to its width of 1942 mm (76.5 inches) and width with mirrors extended at 2218 mm (87.3 inches), careful parking is necessary. The height of 1298 mm (51.1 inches) poses no clearance issues for typical garages. Drivers should measure their garage's width, especially taking into account mirror clearance, to ensure maneuvering room.

The BMW i8 Coupe (I12) was the first generation of its model, introduced in 2013, so it had no direct predecessor in the same hybrid sports segment. However, compared to traditional sport coupes of its era, the i8 was notably longer and wider but maintained a lower height for aerodynamic efficiency. Its innovative hybrid system and unique carbon-fiber construction distinguished it distinctly from conventional predecessors by offering a blend of eco-friendly technology and sports performance.

Compared to similar hybrid sports cars of its time, like the Acura NSX (2016) or Porsche 918 Spyder, the BMW i8 Coupe (I12) is relatively longer at 4689 mm (184.6 inches), lower at 1298 mm (51.1 inches), and moderately wide at 1942 mm (76.5 inches). It emphasizes futuristic design with signature gull-wing doors and a carbon-fiber chassis. While the NSX and 918 focused more on outright performance and power, the i8 balanced size, weight, and hybrid efficiency, making it a standout for drivers seeking a lightweight yet technologically advanced sport hybrid.

The BMW i8 Coupe’s compact yet elongated dimensions contribute significantly to its excellent handling and performance. The vehicle's low height (1298 mm/51.1 inches) lowers the center of gravity, enhancing stability during cornering. The wide stance of 1942 mm (76.5 inches) improves grip, while its curb weight of 1485 kg (3275 lbs) combined with balanced weight distribution between the electric motor upfront and gasoline engine in the rear gives it agile and responsive dynamics. This results in a car that's not just fast in a straight line but also nimble on twisty roads.

The BMW i8 Coupe (I12) was a pioneering plug-in hybrid sports car that combined a 1.5-liter turbocharged three-cylinder engine with an electric motor, delivering a combined output of about 362 horsepower. It was among the first vehicles to showcase sustainable sports performance, featuring a lightweight carbon-fiber reinforced plastic chassis and futuristic design with butterfly doors. The i8 offered advanced aerodynamics, efficient energy management, and minimal emissions for a car in its performance class, setting new standards for hybrid sports cars during its production from 2013 to 2017.
