Unleash your car's potential
The BMW Z4 M40i and the A90 Toyota GR Supra share a joint platform and many mechanical components due to the collaboration between BMW and Toyota. There are however, several technical differences that distinguish each model, tailored to suit their respective brand identities and performance goals.
Here’s a detailed comparison:
Engine and Performance:
BMW Z4 M40i: Equipped with BMW's B58 3.0-liter turbocharged inline-six engine, the Z4 M40i originally delivered 382 horsepower in the U.S. market and 335 horsepower in other markets due to different emissions regulations. This engine is known for its robust power and smooth acceleration.
A90 GR Supra: The Supra also uses the BMW-sourced B58 engine but was initially tuned to produce 335 horsepower globally, and later versions matched the Z4’s 382 horsepower output in all markets. The tuning differences are subtle but aimed at giving the Supra a slightly different performance character, potentially with different boost levels and engine management settings.
Transmission and Drivetrain:
Both models use the same ZF 8-speed automatic transmission, renowned for its quick shifts and reliability. Neither car offers a manual transmission option from the factory, although Toyota introduced a manual option for the Supra in select markets after the initial launch.
Suspension and Handling:
BMW Z4 M40i: The Z4 is tuned more for a balance between sporty handling and comfort, suitable for a luxury roadster. It offers a slightly softer suspension setup, which enhances long-distance comfort while still providing sharp handling characteristics.
A90 GR Supra: Toyota tuned the Supra’s suspension to be stiffer, focusing more on precision and track-oriented performance. The Supra generally has a firmer ride, which contributes to its slightly more aggressive handling dynamics.
Body Style and Weight:
BMW Z4 M40i: As a roadster, the Z4 M40i features a convertible soft-top design, which impacts its overall weight and structural rigidity. Convertibles typically weigh more due to the additional mechanisms and reinforcement required.
A90 GR Supra: Being a coupe, the Supra benefits from a fixed roof, which generally enhances body rigidity and reduces weight compared to a convertible. This structural advantage aids in handling sharpness and overall agility.
Interior and Features:
BMW Z4 M40i: The interior of the Z4 leans towards luxury, with high-quality materials and a comprehensive set of comfort-oriented features. It offers a slightly more refined and feature-rich environment.
A90 GR Supra: While the Supra shares many interior components with the Z4, such as the infotainment system, it has unique styling cues and a layout that emphasizes a sportier driving experience. The material choices and design are tailored to reflect Toyota's performance focus.
Exterior Design:
BMW Z4 M40i: Features classic BMW styling elements, including the kidney grille and a more elegant, flowing design suitable for a premium roadster.
A90 GR Supra: Sports a more aggressive and bold design, inspired by Toyota's sports car heritage, particularly the FT-1 concept. It features dramatic lines, muscular contours, and a distinctive double-bubble roof.
These differences underscore the distinct market positioning of each model—with the BMW Z4 M40i catering to those seeking a luxurious and comfortable roadster experience, and the A90 GR Supra targeting enthusiasts looking for a high-performance sports coupe with a strong emphasis on driving dynamics.
