Red Bull Racing unveils RB10 as pre-season testing kicks off

Ladies and gentlemen, here's the car that will win the 2014 Formula One World Championship... probably. Maybe. The success of Red Bull Racing over the past several years means that the debut of its 2014 challenger is one of the more note-worthy events of the preseason, showing off the latest piece of aerodynamic mastery from Adrian Newey.
Like the Ferrari F14 T, the Red Bull RB10 features a more conventional nose, which still plunges rather dramatically ahead of the front wheels. We're seeing a very interesting split early in the season between the top teams like Red Bull and Ferrari, who are opting for a more traditional design, and the mid-pack challengers, which are being more aggressive with their aerodynamics. Seeing how this plays out during the season will be very interesting. As for RBR's design, it's attractive, but wasn't easy to pen, according to Newey, who found the turbocharged V6s a difficult piece in the new F1 puzzle.
"Whereas the V8s were a very well-known package, with these power units, the engine itself is easy enough to install, but then of course you've got the turbocharger, the intercoolers, and the electrical side in terms of the motor generator units and much bigger batteries," Newey told the official Formula One website.

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 sees a bright future for the luxury sedan

One of the four new models that Infiniti will release in the coming years is an electric sedan previewed by the Vision Qe concept. Investing in a body style that many of the brand's peers and rivals are pivoting away from might sound odd, but executives at Infiniti still see a demand for sedans. "For the U.S. market, the sedan segment is still a very relevant segment. We have a ton of history, and heritage, and hugely passionate fans. So with that kind of passion, we're always getting asks for that kind of piece," Bob Welby, Infiniti's senior director of operations, told Motor1. The publication cited older, Nissan Z-derived sedans like the G35 and the G37 as models that could inspire Infiniti as it brings its first electric sedan to the market. These cars were aimed squarely at European sport sedans like the BMW 3 Series, and they put a much bigger focus on performance than on comfort while remaining pegged on the luxury side of the spectrum. They enjoy a relatively loyal following in 2023. Later known as the Q40, the G37 retired at the end of the 2015 model year and passed the torch to the Q50, which remains in production today but has nearly reached the end of its life cycle. When it retires, it will leave the Nissan-owned brand without a sedan in its range for the first time since its inception: The bigger Q70 retired at the end of the 2019 model year and the full-size Q45 was axed after 2006. In contrast, the current Infiniti lineup includes four SUVs. This focus on high-riding models won't change, even if the sedan sticks around. "SUVs have become another emerging strength of ours over the past decade," Welby said. "That's absolutely going to be part of our story." The next-generation QX80 is notably around the corner. Infiniti previewed it with a close-to-production concept called QX Monograph.   Green Infiniti Electric Sedan
