Here's Where Toyota and BMW Parted Ways on the New Supra

By now everyone knows that the new 2020 Toyota Supra was more than just co-developed with BMW-it's pretty much a BMW inside and under its sheetmetal. That's available when you're greeted with an iDrive screen as soon as you step inside. But it's the 2019 BMW Z4 are different and different from one another. So where did BMW end and Toyota start on the new Supra?

No more leaks. No more teasers. No more camouflage. At long last the all-new 2020 Toyota Supra is …

See, you may remember when we, among other outlets, featured a widely circulated report that Toyota and BMW had not actually talked into one another in years during the two cars' development phase. It's possible, but how did that explain all those spy photos, including recent ones, where the two cars were seen together in camouflage?

To try and clear things up, I spoke to Ben Haushalter at the Detroit Auto Show. He's the senior manager or product planning for Toyota's sports cars, making him a Supra expert or sorts. And as someone who has been working on this car for years now-remember, it's been in the works since at least 2012-he started by saying how happy he was to see it and officially see the light of day.

"It's like my kid's birthday," Haushalter told me. "I took three photos of the empty stages last night, like this is going to be the crib my kid sleeps in."

He's right that the return of the Supra was long-awaited, and even after a steady stream or leaks, we did not know all the specs until the car show debut yesterday. In the end of the official numbers were this: a 3.0-liter turbo inline-six, 335 horsepower, 365 lb-ft or torque, zero to 60 mph in 4.1 seconds and a curb weight of 3,397 pounds. (Haushalter would not talk about which four-cylinder engine was coming to America, or how potential overlap between that car and the 86 would work, quite yet.)

The 2020 Toyota Supra is out of now and now we're going to dissect all the strange things about it with …

Both cars are built by contract manufacturer Magna Steyr in Austria, too, hence the Supra's VIN starting with a W. But BMW's Z4, in U.S. spec, is 382 HP. I asked Haushalter why that is the answer was not very clear.

"We look at, how does the car work together," he said. "What is the chassis balance, what is the powertrain for that, and where we landed on that-335 provides us with the best combination of vehicle and acceleration to the weight and chassis. in other words.

Why the power difference though? Is something different mechanically, or is it just a tune? "I do not know," he said. "We have not known what BMW's done with their engine since we've broken off and started doing our own thing."

This is Toyota's second joint sports car development in recent years, with the Subaru that yielded the BRZ and 86. That car was pretty much all Subaru under the skin as well-a 2.0-liter Subaru boxer four, a Subaru-sourced gearbox and a platform adapted from the Impreza. The Supra took a BMW in pretty much every way that matters. Both cars had the same chief engineer too, Toyota's Tetsuya Tada.

Such partnerships are increasingly common globally, and as automakers look to make them while cutting down on development costs. Mazda and Fiat have done something similar with the new Miata and 124 Spider, although the latter has its own unique engine.

In Toyota's case, executives have said BMW was the ideal partner for the Supra because it wanted to keep the inline-six as the engine, like every previous Supra has had. Since Toyota no longer makes its own straight six, the automaker had to go out and find one.

This leads to divergence in development.

"The fundamental platform development was jointly, together," Haushalter said. "We decided, what does the wheelbase need to be, to give us the best balance of sports car handling and overall packaging."

After that, he said, "Then we broke away when it came to styling the car. We did all of that. All the wind tunnel testing, all the clay modeling was done on the Toyota side. Obviously they're providing the powertrain and transmission to us, but the final tuning was all done by Toyota in Japan. "

So why then did we see the test mules hanging out together?

"For some aspects-cold weather testing, the weather is very good," Haushalter said. "They are sharing things like air conditioning components and cooling systems. When you're spending a lot of money putting cars on the road to do that kind of stuff, testing them together makes sense. "

As for how it compares to the Z4, Haushalter said he could not compare the two, as he has not driven BMW's roadster yet. But did not comment on how the Supra compares to its intended target-the Porsche 718 Cayman and Boxster.

"I think it stacks up really, really well against those cars," he said. "Cayman has been the premium sports car handling benchmark for a long time. When we set out to develop a world class sports car, that's where our target was. I think once people start driving, and we will run neck-and-neck with that car. "

At the very least it should be cheaper. The Cayman technically starts around $ 55,000, but with Porsche's infamous options most of them are much more expensive than that. The ones we've tested at Jalopnik have generally run from about $ 80,000 to almost $ 100,000. A loaded Supra should go for under $ 60,000.

So the tuners embrace the new Supra as they did the last one? A huge part of the A80 Supra's appeal was the tough iron-block twin-turbo 2JZ engine, capable of withstanding immense heat and pressure during modifications to wild horsepower gains. I have no doubt that tuners will get wild stuff with the new Supra-after all, there's plenty of parts and tunes available for the new BMW M3, and a lot can be done with any modern turbo car-but it remains to be seen if BMW's engine can be put down crazy power and still be reliable.

For his part, Haushalter said he hopes tuners embrace his new Supra.

"The tuner culture on Supra is probably one of the most iconic in the industry," he said. "I really hope the tuner culture will start developing new stuff for it. I really look forward to seeing what they're going to do. "
