The best thing about the 2020 Infiniti Q60 Red Sport 400 is its engine. That 3.0-liter twin-turbo V6 makes one of the better noises in the automotive landscape on its way to the 6,800 rpm redline. It makes 400 horsepower and 350 pound-feet of torque, and the engine feels every bit that strong. Peak power is made at a high 6,400 rpm, so it feels linear all the way up to that point. There's no mistaking this for a naturally aspirated engine with the lag off the line, but once it's up and running, there's no obvious fading of power in the higher rpms.
As for the sound … it's also pretty spectacular. We took the Q60 out to some of our favorite deserted backroads and let it rip with a GoPro attached to the bumper. This particular Q60 Red Sport 400 is fitted with a more aggressive exhaust from Infiniti. It's an axle-back exhaust, aptly named the "Axle-Back Sport Exhaust Kit." Infiniti sells the exhaust on its official online parts store — there's one available for the Q60 and another for the Q50. It's currently listed for $707 and is backed by the original factory warranty. Buy it from the store, and then have the dealer fit it to your new (or old) car.
