Are they going to pair the GR V8 with the G20 to make a V12?

You *could* extend a 90-degree V8 with two more cylinders on each side and do it that way. The Build It Yourself youtuber guys demonstrated they could do a totally custom one-off V10 from Ford's Modular engine series using, I think, the Triton V10 block as a starting point but with their own custom made heads (extended V8 DOHC heads as a starting point) and new custom made camshafts. Implementing a dry sump oiling system is their last hurdle. If Ford had done the engine themselves they'd have had millions in R&D to solve what those guys have done on their own with a one-off V-10 DOHC Lincoln sedan.

But custom extending a V8 into a V-12 isn't the usual way to do it if you're a major automaker. And it has already been implied that the GR GT's 4.0L V8 was made by putting two G20E's together...

They likely would use four of the G-series inline-3 engines. At the G16E's 1.6L displacement they'd get a 6.4L. They also have a 1.5L non-turbo CVT-only variant of the I-3 for the non-AWD GR Yaris and supposedly there is now an in-development 1.3L turbo variant for, at minimum, the upcoming not-for-U.S. GR Starlet that they plan to campaign in the Rally4 category.

A 1.3L I-3 x4 would be a 5.2L V-12. A 1.5L I-3 x4 would net a 6.0L V-12.

The usual angle would be at 60-degrees. With balance shafts and other tricks they can do a 90-degree V-12 if they really need more space in the inside of the "V" between the cylinders for induction equipment (turbos, supercharger, electric-assist turbo or supercharger, hybrid equipment, etc.). But they might stick with 60 degrees for the best possible smoothness and internal balance given the kind of ultra-luxury vehicle this is going into.

But doing all of that for an extremely high dollar V-12 car leaves the possibility open for them to also design an inline-6 from two G-series I-3's. It almost makes more sense to design the I-6 from two I-3's first and *then* put two of the inline-six engines in a "V" configuration to get their ultra-exclusive super high dollar vehicle's V-12 engine.

Even if they were to go right to a V-12 design starting only from I-3's x4 it would be so easy for them (with all their money, resources and engineers who definitely want to make a new I-6 of their own) to take one side of the resulting V-12 and fashion a new I-6.

We'll see.

a) Best car is full of shit.
b) The renders are getting worse.

The GR MR2 and... small GR S-FR (the one being co-developed with the new Suzuki Cappuccino and Daihatsu Copen all as RWDs) would be my guess for the second one BestCar is rendering.

The small roadster/coupe is intended as a two-seater and that looks like one. That is unless they're actually not planning to keep their GR86 as a 2+2 on a stretched (after a lot of platform investment from Toyota) Miata MX-5 platform as previously reported. That would be a shame if so as the 2+2 aspect is a big selling point.

Am I crazy for being more excited about the SFR?especially if it has highlighter colors

Yes and no, some of their stories were totally crap and never came to fruition. However, they did accurately depict the following: J300, XF50, J29, and XE30 reskin.

X2! Something fun, small, light weight, and affordable; yes please!

Some screen shots from Forza Horizon 6.

I hate the rear end of this thing and the wheel offsets are all wrong.

Nice. But the logo isn't BIG enough.

I think Hotcars has one of the better CG renders.

 

[Loco38SUP]

All hopes and wet dreams until spy shots start appearing sometime in 2027.

We have at least 2 more years before they hit dealerships.

Just my humble opinion, but I really don't care for that front end look!

 

[KahnBB6]

The last reports on the chassis and body design was that the engineers had decided on a twin rear deck design (one lid for the engine and one for the small trunk) which they consider superior to a single deck design.

Those renders are still reflecting visual roots in the yellow MR2-like "Sports EV" concept from a few years ago. And those were mocked up for the concept reveal event before the engineers decided on the twin deck rear approach... which these renders do not appear to reflect.

The original yellow concept car's front end looked good... but that was a pure design study for the shape. The later red(?) or orange(?) EV concept version that showed a yoke steering wheel interior (barf) had a much worse looking and overly busy front end compared to the original yellow concept shell.

The front end looks better and more realistic than the red/orange one... and the sides still look good while being likely more realistic to manufacture... but the single deck rear wouldn't currently be accurate.

...Not unless the intention is very very narrow top engine access under a glass hatch combined with a likely need to drop the rear subframe with its engine for any major service. That would put it into Porsche Boxster and Cayman level service difficulty. The all three prior generations of the MR2 avoided that.

I'm betting on more accurate and slightly different looking concept images leaking down the road that reflect a more 1990-1999 MR2 SW20 style twin rear deck.
