At its core, the 2022 Lexus IS 500 is a comfortable and stylish sport sedan powered by a naturally aspirated 5.0-liter V8. It's a rare combination since most competitors use turbocharged engines these days. The moment you turn on the ignition and hear the V8 roar to life is enjoyable, and putting the throttle down becomes habit-forming because it sounds so glorious.
Alas, there's more glory in the sound than actual performance. The V8 is rated for a competitive 472 horsepower and 395 lb-ft of torque. And at Edmunds' test track, our test IS 500 accelerated from 0 to 60 mph in 4.9 seconds. That's a little better than most four- or six-cylinder-powered luxury sedans but off the pace of full-on performance sedans such as the BMW M3 (4.1 seconds) or Mercedes-AMG C 63 (3.9 seconds). On the upside, the V8 is supremely smooth. When you're not on the gas, it is as quiet and easygoing as the rest of the IS line.
With all this talk about the engine and horsepower, it becomes easy to forget that the IS 500 is quite capable on twisty roads as well. The IS chassis is tuned for sporty handling but it also has adaptive dampers, so it's good at softening out rough roads as well as helping you carve around corners. The Torsen limited-slip rear differential, which is part of the V6-powered IS 350's Dynamic Handling package, also helps the IS 500 harness the extra power through the twisties by providing the grip necessary to feel planted and secure.
Stopping power in the IS 500 is also upgraded compared to the IS 350 thanks to upsized brakes. In our testing, the IS 500 stopped from 60 mph in 107 feet. That's good for a luxury sedan but not up to full performance sedan standards.
