2027 Toyota GR GT Nerd Out: How It Compares to Ferrari and Porsche

• Toyota's GR GT might be its most exciting car. Like, ever.
• A proper super GT with a 4.0-liter hybridized twin-turbo V8, it's looking to upset the supercar balance.
• But how does it stack up against Ferrari and Porsche? We run some numbers to find out.

Toyota GR GT power-to-weight vs. Porsche and Ferrari

We need to caveat a little before we get started. The first is that not every spec is available from every manufacturer, and the second is that Toyota's are just preliminary. That means things could change by the time the GR GT hits the road, but it's unlikely we'll see extreme changes to Toyota's initial targets.

Toyota's new supercar entrant has the biggest motor of the three. A newly developed 4.0-liter, twin-turbo V8 engine is paired up to a single electric motor (which is also likely housed within the also brand-new eight-speed automatic transmission). The big difference here is that the Toyota is a transaxle, which means the engine is at the front of the car, and there's a long drive shaft that goes from the engine to the back of the car, where the transmission is located. Like in front-engine Corvettes of old, this is to aid in overall weight distribution.

Toyota says its new supercar's target weight is 1,750 kilograms (just over 3,850 pounds).

• 2027 Toyota GR GT weight: 3,858 pounds (Toyota est.) 

The Ferrari and Porsche are both electrified, but in different ways. The 296 GTB uses a 2.9-liter turbocharged V6 that's augmented by an electric motor that's nestled between the crankcase and the transmission (where the bottom of the engine meets the bit that shifts the gears). It's also a plug-in hybrid and can be both charged up at the mains (or via the engine itself) and run on electric power alone.

Ferrari is a little cagey when it comes to weight, only quoting the car's dry weight figure (i.e., when it's as light as possible). Take a quoted dry weight of 3,240 pounds and add in a full 17-gallon tank of fuel (102 pounds), and all the other ancillary fluids like oil for the transmission and engine, coolant for the engine, and even windshield washer fluid, and you get a figure much closer to 3,500 pounds.

• 2026 Ferrari 296 GTB weight: 3,500 pounds (Edmunds est.)

The Porsche, on the other hand, has three electric motors (technically). It uses a 1.9-kWh battery pack to power two electric turbochargers (which have no wastegates and can spin up on demand, essentially dialing out turbo lag entirely). The third electric motor is a permanent-magnet synchronous electric motor housed inside the transmission. These all work to juice up the Turbo S' new 3.6-liter flat-six engine. 

Porsche has said all the electric add-ons add 180 pounds to the Turbo S' curb weight. The last one we put on our scales in 2022 weighed in at 3,696 pounds. Add 180 pounds to that, and you get our estimate. 

• 2026 Porsche 911 Turbo S total horsepower & torque: 701 hp, 590 lb-ft
• 2026 Porsche 911 Turbo S weight: 3,876 pounds (Edmunds est.)

A quick back-of-the-napkin calculation reveals that the Toyota has the worst power-to-weight ratio of the three. 

• Ferrari 296 power-to-weight: 4.27 pounds per hp
• Porsche 911 Turbo S power-to-weight: 5.53 pounds per hp
• Toyota GR GT power-to-weight: 6.02 pounds per hp

This is by no means a definitive measure of what Toyota has done here. No one except Toyota top brass has gotten behind the wheel, and there's a darn good chance Toyota has built something exceptional to drive (that we expect to punch above its rather considerable weight).

Rather, the numbers here should throw into sharp relief the kind of competition the GR GT will have to deal with when it goes on sale in about a year's time. We still can't wait to learn more. In the meantime, below is a chart with all of the GR GT's other specs and how it stacks up to the two proper supercars we've put it against here.
