2014 Infiniti Q50

Avoiding An Identity Crisis... For Now
Infiniti is a brand that has been quietly undergoing major upheaval - and not just with the numbers and letters on its trunklids. Back in December, Nissan's premium brand rankled fans and pundits by announcing it would redo its alphanumeric nomenclature, yet that decision was but a PR speedbump - there are bigger fish to fry. After all, this is a marque that was on the chopping block just a couple of years ago, and now it has a major opportunity to succeed thanks to new investment, new independence (Infiniti is now responsible for its own design, engineering, marketing, quality and human resources), a new global headquarters in Hong Kong, and new marching orders from new leadership that calls for a revitalized and expanded portfolio.
Yet if you think that the Q-based naming convention is the first sign of the brand's new direction, you might have missed Infiniti's biggest signal flare: the 2013 JX crossover. Fine premium three-row crossover that it may be, it's still the first Infiniti in ages that operates without a scintilla of driving entertainment at the core of its genetic makeup. (The last - and perhaps only - previous example was also Pathfinder-based, the 1997 QX4). To be fair, three-row CUVs have a laundry list of priorities before driving enjoyment figures in, but the message the JX (henceforth known as the QX60) sends is clear: Infiniti is going after more segments and more customers. Plans are afoot to expand the company's product line by a whopping 60 percent over the next five years, and in short, that means Infiniti is no longer content to be the unsung Japanese BMW - it needs vehicles that satisfy a wider swath of consumers. Despite all this, Infiniti officials we spoke with were keen to assert that driving pleasure remains very much core to their mission, and to that of this 2014 Q50 in particular.

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:

Infiniti previews modified Q50 Red Sport 400 for SEMA

Infiniti sports sedans are having a bit of a renaissance these days thanks the dirt cheap prices of high mileage G35s and G37s. As such, it's a good a time as any for Infiniti to introduce an aspirational vehicle in the same lineage: a Q50 Red Sport 400 built for the 2023 SEMA Show. The Q50 is probably not a car you've given much thought about in recent years, as it's been hanging around largely unchanged since its introduction in 2014. Infiniti hasn't had a presence at SEMA for most of that time either. This year, the luxury brand has cooked up a Q50 Red Sport 400 loaded with aftermarket accessories for the Vegas extravaganza. The car was built to showcase products from the Infiniti Performance line accessories, which includes suspension bits like upper control arms, rear traction rods, endlinks and more. There's also performance brake pads and a cat-back exhaust with the Infiniti logo etched into the tip. The Q50 show car also adds more coolant into the cooling system with a thicker radiator, a billet-aluminum expansion tank and an auxiliary intercooler tank. Naturally, there's a cold-air intake too. The build was done in part with Mobil 1, who has filled the 400-horsepower twin-turbo 3.0-liter V6 with 0w-20 synthetic.  The most desirable parts of all might be the four lightweight Nismo LM-RS1 wheels. Measuring 19 inches in diameter and 9.5 inches in width, they are available in black, gray, or bronze. The purpose of all this, Infiniti says, is to let owners of the Q50 and Q60 (and older G37s and G35s) know that the company offers a line of parts for customization. It's not the first time Infiniti has tried something like this. Anyone remember the short-lived Infiniti Performance Line (IPL) from 2010? Infiniti's commitment to performance has always seemed half-hearted. Maybe this time it'll stick around for a bit longer.
