Toyota/Gazoo Racing Sport Hybrid Concept II (MR2 Hybrid?!)
#17
According to MotorTrend the name of the concept is meant to honor Hiromu Naruse the Meister of Nürburgring.

The letters “GRMN” translate to Gazoo Racing Meister of Nürburgring — Gazoo Racing being a Japanese motorsports group, while the Meister of the Nürburgring is a nickname for Toyota’s late test driver Hiromu Naruse.

I never looked into the 2GR-FXE before, and didn't realize that the RX450h actually comes in both AWD and FWD variants. Based on posts on the RX forums here, apparently the only difference is the addition of small electric generators to the rear wheels on the AWD; the main part of the gas/hybrid/Atkinson engine is the same either way. That makes me wonder how beneficial such a platform is for sports driving especially given the additional weight and lack of advantage from any weight (re)distribution. It seems to me the real advantage of hybrid AWD in an MR/RR platform is to split as much of the electric stuff away from the gas powerplant as possible.
According to the following report the total output of the Concept II is only 295hp this time, with the 3.5L V6, driving the rear wheels, detuned to 245hp, and the electric motor driving the front wheels. Still decent I guess, if they can keep the weight down.

But yeah, as you said, if the weight really does come in at 2800 this will be fun a car even at 300ish hp. The big issue is keeping the weight down.

It looks and sounds kind of heavy. Seems like it could also quickly price itself out of its' market. Hopefully it, if they make this, it doesn't end up with MR2 size and weighing 3,500 lbs.

The Concept II with the newer 3.5L V6 and less powerful electric motor should weigh around the same as the Concept I if not less.

Thanks for the link. It's funny how they're basically saying it's the RX450h powertrain, but presumably working in the opposite direction relative to the RX. I actually didn't know the RX had transverse engines, which makes it perfect for the MR2. So here it'll basically be the 2GR-FE (rather than the FSE) in the back. (The 2GR-FE is the same engine that goes into the Evora.)

Ya, it's basically the 2GR-FE unit in 2GR-FXE form so not really "detuned", because that's what it makes in the RX450h. Plus, it's based off the 2GR-FE which in gas-only form is rated ~270hp so not as if it was down from the FSE 306hp or something. Of course, I'd prefer to see this get some performance tuning. I'd really love to see something around at least 320-330hp.

Well just guestimating but it would be a low 6/high 5 second car? That is being generous and assuming a weight around 3300lbs compared to the 450h 4500lbs or so. Then it would get maybe 33 or 34 MPG?
Also this generation RX AWD only kicks in when it detects slippage, otherwise its FWD. The last generation 2RX AWD system was 50/50 all time.

I think that "less than 1,500kg" official figure is grossly overestimated. The Concept I, which uses the the older 3.3L V6 driving the rear but with a more powerful electric motor driving the front, pumping out 400hp together, weighed 2,860lbs (1,297kg).
The Concept II with the newer 3.5L V6 and less powerful electric motor should weigh around the same as the Concept I if not less.

Concept cars are not regulated of course, but given that the MR-S that this concept is based on originally weighed 996kg, that the weight difference between the RX350 and the RX450h is 140kg, and that the weight difference between the Auris 1.8 and the Blade 3.5 is 210kg (using Auris/Blade here because it's the only Toyota model with both 1.8 and 3.5 options), the GRMN Concept II should weigh around 996 + 140 + 210 = 1356kg (which is actually heavier than the Concept I).

Man, I remember when an MR-S was spotted at the ring late in it's life cycle with a widened rear end.
This has been in the making forever Should have just made it look like the Volta.
