2015 Infiniti Q70 stretches out in NYC

Infiniti released its refreshed Q70 (the car formerly known as "M") in New York this morning. The luxury sedan is brings with it, quite literally, a big change: it's now the only vehicle in its segment to offer both long- and short-wheelbase options here in the US (other automakers do this in China). Currently, the two-wheelbase sedan strategy is exclusive to the ranks of fullsize players like the BMW 7 Series, Audi A8, etc.
Infiniti has elongated the standard Q70's wheelbase from 114.2 inches to 120.1 inches, in doing so lengthening the car 7.3 inches overall. For the sake of comparison, a standard wheelbase Audi A8 runs 117.8 inches, so the Q70 is no slouch. The extension mostly benefits rear-seat occupants, who are treated to an extra 5.6 inches of legroom. We think the enlargement improves the car's aesthetic, as well.
In addition to the long-wheelbase option, there are a few other tweaks in store for 2015. New head and taillights are the biggest changes, with full LEDs in the back and LED accents in front. Aspects currently seen on the smaller Q50 are evident, as well, such as the "double-arch" grille that comes with mesh-finish inserts. The fascia also includes a new front bumper with integrated foglights. Interior changes seem to be fairly minimal, but that's not necessarily a bad thing. The outgoing Q70 had a spacious (if dated), luxurious cabin with all kinds of high-quality materials.

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:

Grand Prix of the Americas, Day 1 Recap: a city arose in the fields, and it was good

The Circuit of the Americas is the miracle in the fields, the track that no one thought would be finished in time to hold its appointed race. But the Texans got past the turmoil, and even though the heavy machinery was still working on dirt roads as July, come November 18 there was a beautiful, and completed, Formula 1 facility for Travis County to call its own. It was dusty, sure. But it was done, and F1 could come to town.
Infiniti, sponsors of Red Bull Racing, invited Autoblog to watch the first grand prix in America since 2007, and the first GP on a dedicated F1 course since the Phoenix street circuit in 1991. Here's a little recap of what we saw and fount out on day one.
