Yes, the new Toyota Supra is still not out, and this is yet another teaser in what must be one of the most long-drawn car stories ever. Thankfully, the end is near, as next month’s North American International Auto Show in Detroit will host the unveiling of the much-anticipated reborn sports car.

Concept and camo-covered mules aside, we’ve had an (unofficial) look at the A90 Supra’s front end – now, here’s something to tickle our ears. Toyota has released a 30 second video of the Supra accelerating and sliding around, but the red car in the clip is blurred out. The point of the “Sound of Supra” video is for us to hear its 3.0 litre straight-six engine in action.

“There are not many things purer than the sound of a straight six-cylinder engine being put through its paces. So, while we can’t reveal its stunning curves just yet, we recently released it undercover and ahead of its international reveal in Detroit so that you can hear the sound of its harmonious song,” Toyota says.

It does sound good. The clip highlights the sound made by the BMW-derived engine as it pulls away from idle, and you’ll also hear some off-throttle crackle and pop, plus the eight-speed automatic changing gears. Sounds sporty, for sure. What do you think?

The Supra’s sister car is the G29 BMW Z4, which was revealed in August. The third-generation roadster’s top M40i variant comes with a 3.0 litre turbocharged straight-six with 340 hp at 5,000 to 6,500 rpm, and 500 Nm of torque from 1,600 to 4,500 rpm. It does 0-100 km/h in 4.5 seconds and a capped 250 km/h top speed.

However, while both cars share a platform and powertrain, Toyota has done its own work on the Supra. According to A90 assistant chief engineer Masayuki Kai, his team has not spoken with BMW since 2014, when they agreed on the basics.

“We agreed on the packaging, like where is the hip-point for the driver, what’s the wheelbase, the width, location of the fuel tank, A-pillar, and so forth. This was around the middle of 2014, and after that we completely separated our teams. There was no more communication after that,” Kai said.

“Tuning of the shifting, some of the shift shock, shift speed – all of this is specifically designed for our Supra. For the engine, we have tuned it for throttle response and a little more (sportiness),” he added. While we continue waiting, here’s five things you need to know about the new Supra, from chief engineer Tetsuya Tada himself.
