To truly understand how fast the old Supra was, we need to delve into its history, specifically focusing on the models that most enthusiasts associate with the Supra’s speed legacy: the A70 (Mk III) and the A80 (Mk IV).
The A70 Supra: Laying the Groundwork for Speed
The A70 Supra, produced from 1986 to 1993, marked a significant shift for the model. It moved away from its Celica roots and established itself as a standalone, performance-focused grand tourer. While not as universally celebrated as its successor, the A70 laid crucial groundwork for the speed and performance that would define the Supra.
Engine Options and Performance
The A70 Supra offered a range of engine options, depending on the market. The most notable, and the one most associated with performance, was the 7M-GTE. This 3.0-liter inline-six turbocharged engine was a powerhouse for its time.
The 7M-GTE, in its initial iterations, produced around 230 horsepower and 246 lb-ft of torque. While these numbers might seem modest by today’s standards, they were highly competitive in the late 1980s. This translated to a 0-60 mph time in the low 7-second range and a top speed of around 150 mph.
Later versions of the 7M-GTE saw slight improvements in power and torque. However, the A70’s performance wasn’t solely about raw power. Its well-balanced chassis and relatively lightweight construction (compared to later models) contributed to its agile handling and respectable acceleration.
The A70 also came with other engine options, including naturally aspirated versions. However, these models weren’t typically associated with the same level of performance as the turbocharged variants. They catered more to drivers looking for a comfortable and stylish grand tourer rather than an outright speed demon.
