Listen to the 2020 Infiniti Q60 Red Sport 400's screaming exhaust

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 itÂ’s up and running, thereÂ’s no obvious fading of power in the higher rpms. As for the sound Â… itÂ’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. ItÂ’s an axle-back exhaust, aptly named the “Axle-Back Sport Exhaust Kit.” Infiniti sells the exhaust on its official online parts store — thereÂ’s one available for the Q60 and another for the Q50. ItÂ’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. WeÂ’ve driven Infinitis with this engine that donÂ’t have the sport exhaust installed, and theyÂ’re nowhere near as loud. And after driving one with the exhaust, itÂ’s safe to say the factory exhaust is a bit too quiet for our tastes. Starting the cold engine up in the morning is much more satisfying.

In the cabin we hear loud intake whooshes, and on the outside we get to hear its screaming yowl. ThereÂ’s enough sound deadening in the cabin to make it refined and luxurious on light throttle applications, but the exhaustÂ’s sound doesnÂ’t ever disappear. A bit of drone sneaks in on the highway, but if you turn up the decent-sounding Bose audio system, it fades away. More cars could use legitimately aggressive exhausts like this one. Manufacturers continue to pump fake audio into the cabin over the speakers, but itÂ’s not as authentic as something like this. All thatÂ’s missing are bangs and pops on shifts, but we can live without them. Each downshift is delightful, and the overrun is music to our ears. Related video:

2024 Infiniti Q50 prices up $475, start at $44,200

The Infiniti Q50, like some small geologic formation, carries its graceful, aged sculpture into 2024 fearless and unchanged. Whereas in 2023 Infiniti added a new interior color, included Infiniti Premium Care, and increased prices, 2024 only sees higher prices. MSRPs are up $400 and the destination charge rises $75 to $1,150, for an additional premium of $475. Starting sums including destination are:  Q50 Luxe: $44,200  Q50 Sensory: $49,900 Q50 Red Sport 400: $58,050  Every Q50 is powered by a twin-turbo 3.0-liter V6, the Luxe and Sensory trims making 300 horsepower and 295 pound-feet of torque, the Red Sport 400 making the eponymous 400 hp and 350 lb-ft. As standard, all send their power to the rear axle through a seven-speed automatic. Sending power to the front axle adds $2,000.  The Black Opal Edition Package that we expected to be of limited supply returns for 2024. Its black opal iridescent paint job shifts from black to blue to green to purple depending on the light and viewing angle. The paint is matched with satin black badging and an exposed carbon fiber trunk spoiler, adding $2,200 to the price of the sole trim it's available on, the Q50 Red Sport 400. The package traces its lineage to the legendary iridescent Midnight Purple II, a color introduced on the R34 Nissan Skyline GT-R in 1998, and counts recent reboots elsewhere in the Nissan range with the 2014 GT-R with a Midnight Opal paint job and the 2022 GT-R T-spec in Midnight Purple.    It's understandable that a brand built on premium and sporty offerings doesn't want to give up its last unabashedly sporty offering, but this seems like a natural time to again wonder what is the endgame for the Q50, the final car in Infiniti's U.S. lineup. Automotive News reported over the summer that Infiniti showed its U.S. dealers a fastback sedan called a "striking evolution" of the Q70 boasting a longer wheelbase and shorter overhangs, a full-width headlight and taillight, and a "sporty and Porsche-like" rear end. That's anticipated in 2026. Maybe then the Q50 will be allowed to go off somewhere and rest.

Infiniti's variable compression engine in the 2019 QX50 is the first of its kind

The world's first variable compression ratio engine is here, in a production car. That car is the 2019 Infiniti QX50, debuting this week at the Los Angeles Auto Show. The midsize crossover has seen a refresh that has brought it an all-new platform together with new driver assist features, but it's the engine that's the centerpiece here. Nearly everything is continuously variable under the hood of the QX50 – not only the new shift-by-wire XTRONIC CVT. The new VC-Turbo gasoline engine is able to change its compression ratio from 8:1 to 14:1, or anything in between depending of the driving situation; whether there is need for top-end power or turbodiesel-like torque from low revs, or optimized fuel economy. The pistons' reach is continuously adjusted by an electric "Harmonic Drive" motor, which controls a multi-link system, affecting the top-dead-center of the pistons and changing the compression. The engine can also switch between efficiency-maximizing Atkinson cycle and regular combustion cycle, on the go – and there's both multipoint injection and gasoline direct injection employed. The result is 268 horsepower at 5,600 rpm and 280 pound-feet of torque at 4,400 rpm; good figures for a 2.0-liter four-cylinder gasoline engine with a single-scroll turbocharger. Infiniti says that the FWD version's fuel economy of 27 miles per gallon combined is 35-percent better than the previous-generation V6 engine; in AWD guise, it reaches 26 mpg, which is a 30-percent improvement. The new engine is pretty much all-aluminum, but the vaguely magical-sounding "transformative multi-link components" behind the variable compression system are made from high-carbon steel alloy. The engine's multi-link system also enables it to do away with any balancing shafts, and Infiniti compares its smoothness to a V6 rather than a regular four-cylinder. In addition to the aforementioned tech, the VC-Turbo engine has the world's first active engine mount vibration damping system to smoothen its operation even further. Related Video:
