Infiniti Q30 spied again

The Infiniti Q30 is back in the news thanks to the imminent debut of the QX30 Concept as its crossover counterpart at the upcoming 2015 Geneva Motor Show. The siblings are Infiniti's entrants into the popular premium compact ranks, and the standard hatchback was recently spotted in Europe with the least amount of concealment yet. Granted, this tester is still pretty heavy camouflaged, but this is a lot better aesthetically than the previous garbage-bag-covered look. While the pattern makes specifics hard to discern, the translation from the motor show stand to the road appears to be leaving the Q30 Concept's styling largely intact. Up front, the squinting headlights and swollen-rectangle shape of the grille remain similar, and while they are pretty hard to spot, the slashes down the side are faintly visible from some angles. The rear hews even closer to the original design with a comparable shape for the taillights and hatch, but exhausts are much smaller on this test car. Underneath the skin, the Q30 reportedly shares its platform with the Mercedes-Benz GLA-Class, and the engine is also expected to be the 2.0-liter turbocharged four-cylinder available in Mercedes' compact lineup. Official details should start spilling out soon, though, because Infiniti wants production of the hatchback to begin in 2015 at the Sunderland plant in the UK. A launch for the US market is expected in 2016. Featured Gallery Infiniti Q30 Spy Shots Image Credit: CarPix Spy Photos Infiniti Hatchback Luxury infiniti q30 infiniti q30 concept

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.

Formula 1 seeking independent engine supplier

Formula 1 could get a new engine supplier in the near future, if Bernie Ecclestone and the independent teams gets their way. According to Autosport, the FIA is soon to open the contract up for bids, and there are already several manufacturers that have expressed interest. Currently Mercedes, Ferrari, Renault, and Honda supply engines – both to their own premier teams (Red Bull and McLaren for the latter two) but also to other teams like Williams, Sauber, and Toro Rosso. Because the new turbocharged V6 hybrid power units cost those four suppliers so much to develop, they're charging their customer teams big bucks – around $20-30 million per season – to provide the engines. These costs are much higher than the $10 million or so it used to cost to purchase a V8 engine under the previous regulations. Ecclestone figures it's time to bring in another supplier who will not run their own team and not play favorites, but will supply engines to private teams at a lower cost. There are already a number of potential suppliers under consideration. One of them is said to be Cosworth, which has a long history in the series stretching back to 1963. The British firm stepped back between 2007 and 2009, returned in 2010, and dropped out again after 2013. The development could be of particular benefit to Red Bull, which has been unable to find an engine supplier and could be forced out of the series as a result. The team has long been powered by Renault, but that relationship has grown sour. And the other three engine manufacturers have not been forthcoming in offering an alternative arrangement for the team.
