2022 Alpine A110 E-ternite (Prototype) Dimensions, Size & Specs

The Alpine A110 E-ternite prototype has a curb weight of 1378 kg (around 3,038 lbs). This relatively light weight contributes significantly to its agility and performance characteristics. A lighter curb weight improves acceleration, handling, and braking efficiency, which are crucial for sports cars like the Alpine A110. Given this is an electric prototype, maintaining a lightweight approach helps offset the additional weight of batteries typically found in electric vehicles, thus preserving the dynamic driving experience Alpine aims to deliver.

The Alpine A110 E-ternite prototype features front rims sized 8.5J x 18 and rear rims 7.5J x 18, paired with tire sizes 245/40 R18 at the front and 215/40 R18 at the rear. These tire dimensions provide a balance between grip and comfort, enhancing cornering stability and road handling. The wider front tires (245 mm) ensure strong contact with the road, improving steering response, while the slightly narrower rear tires (215 mm) help with agility and reducing rolling resistance. This setup helps the car achieve precise handling characteristics expected from a performance coupe.

While exact dimensions for the Alpine A110 E-ternite prototype are not officially released, the car is based on the Alpine A110, which has a compact footprint roughly 4128 mm (162.5 inches) long and 1798 mm (70.8 inches) wide. Standard residential garage doors typically measure around 2438 mm (96 inches) wide and 2134 mm (84 inches) tall, making the Alpine A110 E-ternite a suitable fit for average garages. Its low height (around 1252 mm or 49.3 inches) further ensures it can easily clear standard garage openings without clearance issues.

The Alpine A110 E-ternite prototype is an evolution of the current Alpine A110 coupe and is expected to closely mirror the predecessor's compact and lightweight dimensions. Since official size figures for the prototype are not disclosed, it's believed that the E-ternite maintains the original's length (~4128 mm/162.5 in), width (~1798 mm/70.8 in), and height (~1252 mm/49.3 in). Differences mainly come from design refinements and electric powertrain packaging instead of significant dimension changes, keeping the same nimble and agile footprint as the internal combustion predecessor.

The Alpine A110 E-ternite prototype, with a curb weight of 1378 kg (3038 lbs) and compact dimensions resembling the original A110, stands out among electric sports coupe concepts for its lightness and agility. Compared to other electric sports prototypes—which often weigh over 1600 kg due to battery mass—the E-ternite’s relatively low weight suggests Alpine's focus on lightweight materials and efficient packaging. Its dimensions make it smaller and likely more maneuverable than larger, heavier electric sports coupes like the Porsche Taycan or Tesla Roadster prototype, targeting a purist driving experience within the electric sports segment.

The Alpine A110 E-ternite prototype aims to preserve the original Alpine A110’s celebrated lightweight and compact design, but with an electric powertrain. The key design goal is to maintain agility, precise handling, and driving purity by ensuring the car has a low curb weight of 1378 kg (3038 lbs), despite the addition of batteries. Alpine achieves this through optimized structural components, lightweight materials, and compact packaging, balancing the challenges of electrification with the brand’s sportscar heritage focused on nimble dynamics and a small footprint.

The Alpine A110 E-ternite prototype uses 18-inch rims sized 8.5J and 7.5J with tires 245/40 R18 (front) and 215/40 R18 (rear), a common sizing in sport compact cars and track-focused vehicles. This sizing ensures a wide availability of aftermarket tires and rims for enthusiasts looking to upgrade for performance or aesthetics. The staggered setup (wider front tires) offers flexibility for tuning grip and steering response. However, any aftermarket modifications should consider the prototype’s weight distribution, suspension setup, and intended use to maintain balanced handling.

The Alpine A110 E-ternite was introduced as a prototype concept in 2022, marking Alpine's exploration into electric sports cars. There are currently no official announcements regarding full production or commercial availability. Prototypes like the E-ternite often serve to showcase technology, design direction, and test public interest. While Alpine indicates a clear interest in electrification, potential production versions depend on technological developments, market demand, and regulatory factors. Enthusiasts can expect Alpine to build on this concept for future electric models, but at this stage, the E-ternite remains a one-off showcasing future possibilities.

Despite being an electric prototype, the Alpine A110 E-ternite focuses on retaining the dynamic qualities that defined previous A110 models — agility, balance, and precision. The relatively low curb weight of 1378 kg (3038 lbs) helps offset the typical weight penalty of electric batteries. Its compact size, balanced tire setup, and chassis engineering enable sharp handling and driver engagement. Alpine’s expertise in lightweight construction and sports car tuning is applied to ensure the electric powertrain does not compromise the driving experience, thus maintaining the brand’s heritage of creating fun, driver-focused sports cars.
