Featured Scoop: Next GR Supra will be an EV

They seem to be emulating Tesla, both with this and the gen 5 Prius. Not blatantly, but... Could do worse.

 

Okay that should be pretty sick...

My next Supra challenge will be finding out if the one I saved on my PlayStation memory card still loads on Gran Turismo (og) as my daughter is almost old enough to benefit from video games. That was an incredible car...

 

There is also such a thing as sequential turbocharging, where you use a very small turbo for instant response but it wastegates out pretty quickly... just as the secondary larger turbo has spooled up to maintain boost the rest of the way up the curve.

I can't tell you what exactly it was linked to, but sequential boost was kind of a phase that the automotive world went through enthusiastically and left behind just as enthusiastically. I understand that there is a "second wave" in progress but I couldn't tell you if this were part of it.

 

You can just have 3 cylinders feed each turbo, like on a V6. BMW and Stellantis have done that. Since the current Supra is mostly BMW, this one probably is also using a BMW power plant.

Today's supra uses a twin scroll turbo charger on B58 bmw engine. Bmw's next M3 will have a similar engine S58, with 2 turbo chargers matching this rumor's power. I believe they each serve 3 cylinders which improves turbo lag versus having one bigger turbocharger.

For the roughly 400 hp supra a twin scroll works, but this beast will have over 500 hp. For efficiency mercedes is using a more expensive electric turbo instead of twin turbo chargers. In the amg C43 produces about 400. At low rpms when the engine needs boost the electronic supercharger spins it up with no lag. The C43 uses a 48V mild hybrid system since it needs a lot of power to spin up the turbo, and can recapture energy from the turbo. The upcoming C63 will come out later this year is a phev with a 6.1 kwh battery but a motor that can add 202 hp in up to 10 second bursts. The 2L I4 makes 469hp in this configuration making a combined 671hp to replace a v8. Garrett is making this f1 tech turbocharger for mercedes, and I believe will sell to anyone, so maybe toyota could drop one in the GRMN supra and get around 600 hp from it. My guess is the rest of the S58 engine is up for the task, but you might need a bigger intercooler.

 

I don't get that sense. Tesla doesn't have a monopoly on good looks. In fact the new Prius looks better than Model 3.

 

It's hard to say when Stellaris is talking out of both sides of their face. Does all electric mean their entire fleet? Or does it mean some of their cars will be all electric. Considering they're chatting up their turbo, most likely the latter.

 

Volvo's all electric statement, and China's EV policy, includes mild hybrids.

 

It is only 2023, stellantis said their plan for 2030 last year was 100% BEV in EU and 50% BEV in the US. I assume other countries will have a higher percentage of non BEV vehicles. These are aspirational goals and I do not expect that they will meet them, but hopefully will get mostly there.

They did invest in better turbo charging technology to follow BMW and then Mercedes to create a 3L straight 6 that replaces their v8s. In the case of the Dodge this beast will replace the 6.4L V8 hemi. I would expect the engine to be viable at least in phevs for the next 20 years, but will be much less important in 2035. I expect by 2030 most light pick up trucks will still have engines, but the v8s will be gone and their will be a lot of turbocharged V6 and I6 engines in phev configuration. The aluminum block 3L I6 will be around 200 lbs lighter than the iron block V8 yet will deliver better fuel economy and more power.
