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.

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.

Infiniti Q60 Concept a shadowy vision of future coupe

Until now, the Infiniti Q60 has been one of the brand's holdovers from its old naming scheme and previous design ethos, as a rebadged G37 Coupe. Those times are coming to an end though, because we are getting our first glimpse at a Detroit Auto Show-bound concept that previews the next-gen two-door. Infiniti's freshly released teaser shows the sport coupe concept in shadowy silhouette. Based on this photo, we can see that the Q60's design features delicately swooping lines with a touch of hard-edged contrast coming from sharp creases in the body. Portions of it, especially towards the rear, bring a little of the Q80 Inspiration from the Paris Motor Show to mind. A previous rumor suggests this shape is very close to the actual design of the production version. Infiniti subtly reiterates that in its release by saying the concept foreshadows the styling we might see in future products from the luxury automaker. Scroll down to read the concise announcement for the Q60 concept. Infiniti Q60 Concept: The Power of Exhilaration December 12, 2014 Hong Kong – Infiniti today gives an intriguing first look at the premium sports coupe concept to be displayed at the 2015 North American International Auto Show (NAIAS) in Detroit. Muscular lines are revealed in the silhouette of the Q60 Concept: pure, well-defined contours, making the concept's intentions easy to understand at first glance. Overall proportions and full-sized wheels placed out at the corners of Q60 Concept make an unmistakable design statement and add to the exhilaration of the performance coupe. This latest concept builds upon the design language seen on recent Infiniti concept cars, foreshadowing the strong visual consistency to be a key ingredient of products in the future Infiniti lineup.
