A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

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:

2020 Infiniti Q60 Infotainment Driveway Test | Baby steps forward

Infiniti is slowly coming round to the modern age of infotainment systems this year, and our first taste of that is in the 2020 Infiniti Q60 Red Sport 400. This performance coupe has an updated system in it that, while it looks a whole lot like it did before, represents a step forward for Infiniti. Most importantly, Infiniti has finally added Apple CarPlay and Android Auto functionality for 2020. Every new 2020 model year car should ship with the smartphone connection technology baked in, and Infiniti has finally gotten with the program this year on nearly all of its cars (QX60 is the holdout). The delay might have something to do with Nissan/Infiniti's reluctance to share customer data to Apple and Google, or perhaps Infiniti was waiting to roll out a broader interface update, but either way, the hardware they've applied it to would seem to be the same as before.  2020 Infiniti Q60 infotainment system View 9 Photos This updated interface also has upgraded graphics for a smoother experience. The improved performance is acceptable, but the problem with Infiniti’s InTouch twin-screen system has always been more than just its lack of speed. Compared to the advanced infotainment systems from Germany, InTouch looks and feels about five years behind the curve. Mercedes' MBUX, BMW's iDrive and AudiÂ’s MMI all respond with the speed and vigor we expect from top-shelf smartphones these days. The Infiniti's UX is as uninspiring as it gets. Simple, colored boxes fill the bottom screen, and a difficult-to-reach navigation system fills the top. Unfortunately, Infiniti decided to drop Apple CarPlay and Android Auto functionality into the top screen, too — there was hardly any choice, as important car functions and settings are found on the bottom. Reaching all the way to the top row of icons on Spotify while driving is not easy when theyÂ’re all the way up there! And I promise you, my arms are normal length for a 5-foot 10-inch individual. A widescreen solution is better, which we once again found to be the case in the new Toyota Highlander. Another new feature this year is the addition of a WiFi hotspot for up to seven devices. Once again, itÂ’s a feature thatÂ’s been offered for years from other manufacturers, but itÂ’s still worth noting that a new Infiniti you buy will have it. After using the system every day for a week, nothing truly got on my nerves. It works, albeit slowly and without flare or excellence.
