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:

Edmunds ranks the best used cars for 2013

When people ask us what car we would recommend for them, it's usually not easy to answer. To make a useful recommendation we must consider which of the numerous vehicle segments fits their needs best, and then choose one of the many vehicles offered in each segment. For some people, new cars don't meet their expectations of value, because they lose so much of it the moment they are purchased and driven off the dealer lot. For them, there's always the used-car market, where great deals can be found, but cars' histories of reliability and maintenance records - and perhaps that Certified Pre-Owned warranty - become ever-important factors playing into purchase choice.
To help out, Edmunds has done us the favor of assembling a list of the best used vehicles money can buy, covering model years 2006-2011, according to what it considers the most important criteria when shopping for used autos: reliability, safety, value and availability. That means unreliable, unsafe, super-expensive or limited-edition models don't appear on the list, but instead cars from each segment that are more likely to satisfy the general population.
There are some real goodies on the list, including but not limited to vehicles such as the capable Honda Fit, the cultish Honda Accord coupe (which can be had with a 240-horsepower V6 and a six-speed manual transmission some years), and the powerful Chevrolet Corvette. While Edmunds' choice of the Volvo C70 for best used convertible baffled us at first (not that it's a bad car), it redeemed itself by stating that the Mazda MX-5 still is an unofficial top choice if you don't require more than two seats.

Infiniti QX80 Monograph: Not just luxury, 'upscale luxury'

We've been getting a slow rollout of news about the new Infiniti QX80 Monograph mega-SUV for the past week or two, and Infiniti provided more details Tuesday about its concept car at the New York Auto Show, saying the mega-SUV is a combination of "luxury with a commanding presence" and "the ultimate expression of futuristic luxury SUV design." Infiniti says the car embodies, not just luxury, but "upscale luxury." The company says the concept's design language incorporates a mix of geometric and organic shapes, including character lines and aluminum trim that were actually intended to make the big SUV appear even bigger than it actually is, which is more than five meters long, so perhaps 17 feet, more than 6 feet wide and about 6 feet tall. The most striking features are the headlamps, which become long, slender lines that wrap around the front corners, then taper into light bars that end at the doors in sculptured rear-view cameras in lieu of side mirrors. The car also has large, functional fender vents to divert air to the engine, and despite all that luxury it is still SUV enough to have an underbody cover protecting the underside - and improving aerodynamics. Likewise, an aerofoil between the tailpipes is said to improve airflow in the SUV's wake. It's a big, beautiful rig.
