With electrification now playing an increasingly important role in the auto industry, large naturally aspirated engines are becoming a rarity. Only a few manufacturers still offer factory V8s without forced induction with Ford and Lexus being two very good examples. Which company sells more powerful and faster V8-powered vehicles? Let’s find out.
The answer to the first question is relatively easy. The output figures for the 2022 Lexus IS 500 used in this video show a naturally aspirated 5.0-liter engine producing 472 horsepower (347 kilowatts) and 395 pound-feet (536 Newton-meters) of torque. An eight-speed automatic gearbox sends power to the rear wheels. The vehicle has a curb weight of 3,980 pounds (1,805 kilograms).
To that end, the 2022 Ford Mustang GT uses a naturally aspirated 5.0-liter V8 engine with 450 hp (331 kW) and 410 lb-ft (556 Nm) of torque. A six-speed manual gearbox is responsible for transmitting power to the rear wheels. The Mustang GT’s curb weight is 3,932 lbs (1,783 kg).
As you can see, Lexus has a slight advantage over Ford in terms of maximum power. It’s also a little heavier, but it probably won’t affect the live drag races the two cars do in the video at the top of this page. However, the lack of an automatic gearbox in the Mustang will probably make the difference.
This is definitely a very close battle – you can tell by the numbers. We’re not going to spoil the results, but we’ll just let you know that a Mustang GT with a 10-speed automatic would probably be a better fit for the IS 500 in these specs. Also, Mustang drivers don’t really make gear changes, especially in some of the rolling races.
However, both cars are very fast in both the standing-start and rolling-start races. It would be interesting to see a rematch with the automatic Mustang GT and a faster gear change. Enjoy naturally aspirated V8s as soon as they might be gone forever.
