Weighing in at 1386 kgs (3055 lbs) places the McLaren 620R 4.0 V8 Turbo in a similar weight category as the 2025 Ferrari 296 3.0 V6 Speciale and the excellent 2024 Maserati GT2 Stradale, give or take 50kg.

The McLaren 620R shares the same bhp with the 2025 Maserati MCPURA Cielo 3.0 V6 Twin Turbo (621 bhp)

In terms of pure power the 3994cc 32 valve, V 8 engine produces around 611 bhp (455 kW) @ 7000 rpm which is comparable to the 2025 Maserati MCPURA Cielo 3.0 V6 Twin Turbo (621 bhp) and also the 2025 Maserati MCPURA 3.0 V6 Twin Turbo (621 bhp).

The Twin Turbo V 8 throws out 457 lb-ft (619.6 Nm) @ 3500 rpm placing it with cars of similar torque performance figures such as the 2025 Maserati GranCabrio 490 (443 lb-ft) or the 2025 Maserati GranTurismo 490 (443 lb-ft).

Power to Weight:

If you look at both power or torque of the 2019 McLaren 620R in comparison with its weight you get a much more accurate idea of its real world performance.

The 2025 Lamborghini Fenomeno V12 (465.0 bhp per ton) has similar Bhp Per Ton stats as the McLaren 620R.

The McLaren 620R has a power to weight ratio of 440.8 bhp per ton. Bhp per ton figures of the 2019 620R 4.0 V8 Turbo means you're competing with the 2025 Lamborghini Fenomeno V12 (465.0 bhp per ton) and the equally quick 1992 Caterham Super 7 JPE (463.8 bhp per ton).

Torque to Weight:

If you agree with the late great Carroll Shelby then arguably an even better indicator of potential performance is Torque!. However, torque isn't the whole story, you also need to compare weight as well for more real world comparisons such as torque per ton.

The McLaren 620R 4.0 V8 Turbo generates around 329.7 lb-ft per ton. So if you're looking at what cars perform similarly either on the drag strip or at the traffic lights using torque to weight as a benchmark, then look no further than the 2022 Ferrari 296 GTS 3.0 V6 Twin Turbo Hybrid (354.5 lb-ft per ton) or the similarly performing 2022 Ferrari 296 GTS Assetto 3.0 V6 Twin Turbo Hybrid (354.5 lb-ft per ton).

Top Speed:

Some modern performance cars are often artificially restricted particularly when it comes to max speed. 155 mph top speed restrictions are often used as part of the German 'Gentleman's Agreement' for example, so be cautious when using maximum speed figures. The 2019 version of the McLaren 620R 4.0 V8 Turbo has a maximum speed of 200mph.

Top Speed of the 2019 620R equals the Maserati GranTurismo Trofeo (199 mph)

If maxing out your car on the AutoBahn is your thing and you're wondering what has a similar top end performance to the 2019 McLaren 620R 4.0 V8 Turbo then there's the slightly slower the Maserati GranTurismo Trofeo (199 mph) or how about the impressive Porsche 911 Turbo 991 II (199 mph).
