Details about Section 2 of Cars That Secretly Share the Same Engine
The collaboration between Toyota and BMW in developing the fifth-generation Toyota Supra and the BMW Z4 has led to the sharing of significant components, including the engine. This partnership has resulted in two distinct sports cars that, despite their unique brand identities and design philosophies, share a common powertrain.
Both the Toyota Supra and the BMW Z4 are equipped with BMW’s B58 engine, a 3.0-liter turbocharged inline-six. In the Supra, this engine produces 335 horsepower and 365 lb-ft of torque, while in the Z4 M40i, it delivers 382 horsepower and 369 lb-ft of torque. Despite these differences in output, the engine’s fundamental design remains consistent across both models. (roadandtrack.com)
The decision to use the B58 engine was a result of Toyota’s desire to incorporate a straight-six engine into the Supra, a characteristic that had been a hallmark of previous Supra generations. However, Toyota did not have a current inline-six engine in production at the time. BMW, renowned for its expertise in straight-six engines, provided the B58, which met Toyota’s performance and reliability standards. (motortrend.com)
In addition to the shared engine, both vehicles utilize an eight-speed automatic transmission sourced from ZF, a leading manufacturer of automotive transmissions. This transmission is paired with a rear-wheel-drive layout, contributing to the dynamic driving experience characteristic of both sports cars. (topspeed.com)
The collaboration between Toyota and BMW extended beyond the engine and transmission. The chassis and platform of the Supra and Z4 are also shared, with both vehicles being produced at the Magna Steyr plant in Graz, Austria. This shared production facility underscores the depth of the partnership between the two manufacturers. (motorauthority.com)
Despite these shared components, Toyota and BMW have tuned the Supra and Z4 differently to align with their respective brand identities. The Supra is positioned as a more track-focused vehicle, while the Z4 offers open-top motoring. These distinctions are evident in the vehicles’ handling characteristics, suspension setups, and interior designs. (gaukmotorbuzz.com)
In summary, the Toyota Supra and BMW Z4 exemplify how automotive manufacturers can collaborate to share engine technology while maintaining distinct brand identities and design philosophies. This partnership has resulted in two high-performance sports cars that, despite their similarities, offer unique driving experiences to enthusiasts.
