Panoz and DeltaWing suing Nissan over BladeGlider concept

Similarity is bound to occur in an industry where most of the products follow the same basic formula. But once in a while a new design comes along that doesn't quite reinvent the wheel, but comes pretty damn close. The DeltaWing project was one such design - and Nissan, the car's designers allege, stole that design.
After the DeltaWing proposal was rejected by the IndyCar series, its creators took it to Le Mans and brought Nissan on board to supply the power. Nissan subsequently pulled out of the program and came out with the ZEOD RC hybrid racer (right), bearing a suspiciously similar design with an unusually narrow front track at the end of a long nose cone, and a wider track at the back. The Japanese automaker then displayed the BladeGlider concept (below, right) at the Tokyo Motor Show, envisioning a translation of the same formula into road-going form.
The similarity did not escape Don Panoz, who - after making sports and racing cars under his own name and founding the now-defunct American Le Mans Series - was a central figure in bringing the original DeltaWing to life. Now Panoz has filed a lawsuit against Nissan, soliciting the courts to issue a cease-and-desist order on both the ZEOD RC and BladeGlider projects, naming Nissan motorsport chief Darren Cox and Ben Bowlby (who defected to Nissan from the DeltaWing program) as part of the suit.

We drive the cars of Furious 7... in Forza Horizon 2 [w/video]

On March 27, Turn 10 Studios, the folks behind the Forza Motorsport series, and Universal Pictures, the studio responsible for the Fast and Furious franchise, gave us a match made in heaven, announcing a "standalone expansion" featuring the two franchises. Called Forza Horizon 2 Presents Fast and Furious, it features the cars from the latest film installment, unique missions and the voice-acting of Chris "Ludacris" Bridges, who plays tech guru Tej Parker on camera. A Fast and Furious video game? Seems like a no brainer. It gets better. Rather than limiting the Fast and Furious Edition cars to the expansion game, Turn 10 made them available through one of their (some may say notorious) downloadable content packages. Eight of the expansion's 11 cars were made available for just $4.99 (the only cars that weren't included were the Fast and Furious Edition Nissan GT-R, while the Bugatti Veyron Super Sport and McLaren P1 are already available in-game). What's cool ais that the cars featured in both games are visually identical to the vehicles driven by the stars of Furious 7. Each in-game car has an on-screen parallel that plays a role in advancing the film's story. Considering that we're unlikely to score seat time in Dominic Toretto's real Dodge Charger, then, we figured we'd take to the game and test the car in the digital realm. We've got nine little cluster reviews, covering the cars both in the game and how they appear in the movies. And don't worry, there are no major spoilers here. Click on for the cars of Forza Horizon 2 Presents Fast and Furious. 1970 Dodge Charger R/T Fast and Furious Edition Supercharged 7.2L V8 / 900 HP / 663 LB-FT The one vehicle that is mandatory in a Fast and Furious video game, Dom's hot-rodded 1970 Dodge Charger, is as much a character in the films as its driver. Furious 7 marks the fourth appearance of this Mopar beast in the series. Not surprisingly it's a handful to drive, wildly quick and with a four-speed transmission packed full of very tall gears. But beyond that, it's arguably the coolest of the FF Edition cars. This black beauty is exactly as it appears in the latest installment of the film, with the video game version featuring intricate little details, like the moving parts on the BDS supercharger. It's an iconic car, and it's treated as such in the game.

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.
