Infiniti prices renamed 2014 QX50 and QX80 crossovers

Earlier this week, Infiniti revealed the pricing for its two midsize crossovers, but now it has announced the pricing for its renamed bookend utility vehicles, the compact QX50 crossover and the fullsize QX80 SUV. Those looking for a smaller luxury crossover will be glad to learn that the 2014 QX50 now starts at $34,400* (a price drop of $2,500 compared to the 2013 EX), while pricing for the 2014 QX80 will remain the same as the 2013 QX56, starting at $61,350* (*prices do not include $995 for destination).
In terms of packaging, the QX50 will carry over unchanged, but the QX80 gets a new Backup Collision Intervention system as a part of its optional Technology Package. All of Infiniti's 2014 QX utility vehicles are on sale now, but for more details about the QX50 and QX80, scroll down for the official press release.

Infiniti Q30 goes full monty before Frankfurt

Infiniti is finally tearing off the camouflage and showing the world what the Q30 luxury hatchback actually looks like. Set to make a full debut Frankfurt Motor Show on September 15, the five-door marks the entry of the Japanese premium brand into the compact hatch ranks. The company's designers did a fantastic job of bringing the major elements from 2013's concept to the street, though. Like the earlier design, the production Q30 wears Infiniti's rounded rectangle grille and a chrome strip along the edge of the hood. The headlights are also left squinting from the concept. The only major change to the front end is an adjustment to the lower air dam to make it a little more realistic for production. Sadly, Infiniti is only providing this single front three-quarters perspective on the upcoming five-door for now, but check out the C-pillar in the background to spot the similarly pointed design there, as well. The changes are actually more noticeable when comparing the Q30 with its platform-mate, the QX30 compact crossover concept. The hatchback noticeably softens many of the CUVs swoopy lines to be a bit more mainstream. This is especially true along the front where the big air intakes from the QX are made significantly smaller. Production of the Q30 is slated to start in Sunderland, England, by the end of the year. They should actually arrive in showrooms there before the calendar runs out. Still, we're looking forward to Frankfurt for a more complete view of Infiniti's little luxury hatchback.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
