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's fastback 2021 QX55 crossover shows its stylish rear end

First announced in August 2019, the Infiniti QX55 will finally make its global debut on Tuesday, November 17. Nissan's luxury division released a preview image that gives us the best look yet at the next addition to its range. The QX55 is closely related to the QX50 crossover under the sheetmetal, but it stands out from its more family-friendly sibling with a rakish, fastback-like roofline that will inevitably attract the coupe label. It will be to the QX50 what the BMW X4 is to the X3. Although we haven't seen its front fascia yet, Infiniti's preview image shows the rear end wears horizontal LED lights that stretch deep into the quarter panels, along with a roof-mounted spoiler. We were pleasantly surprised by the QX50's upmarket interior, so we're expecting a comparable degree of opulence in the QX55. It's too early to tell if Infiniti will simply copy the 50's cabin layout and paste it inside the 55, or if the latter will receive a look of its own. Similarly, technical specifications won't be published until the model's introduction. We expect that the VC Turbo four-cylinder engine, which was a finalist for the 2019 Autoblog Tech of the Year award, will appear on the roster. All-wheel drive will certainly be available, and Infiniti may offer an entry-level variant with front-wheel drive. Infiniti will present the 2021 QX55 online Tuesday during an event that will star singer Aloe Blacc. It will stream the concert-unveiling cross on its various social media platforms starting at 8:55 p.m. Eastern time, 5:55 p.m. Pacific time. Built in Mexico, the model will arrive in American showrooms in early 2021 with a base price pegged above $40,000. What's next? The QX55 will stand out as the first model released under Infiniti's Nissan-Plus strategy, which was presented as a way to cut costs and boost profits by increasing the number of components it shares with its parent company. However, leaning more heavily on Nissan will not dilute its image or its products, according to executives. Stylists are in the process of overhauling Infiniti's design language, and the brand's reboot will put a major emphasis on technology. Looking ahead, the QX will be followed by the next-generation QX60, which is tentatively due out in 2021 as a 2022 model, and by the company's first series-produced electric car. Related Video:
