2015 Nissan GT-R Nismo to hit 60 mph in 2 seconds?

Here's your daily dose of incredulity - AutoExpress is reporting the 2015 Nissan GT-R Nismo will hit 60 miles per hour in two seconds. Okay. The report comes from an unnamed source that AE spoke with at the Goodwood Festival of Speed, and would mean that the GT-R Nismo, a car that will likely sit below $150,000, will be able to outsprint (over short distances) a 1200-horsepower, $2.58-million Bugatti Veyron Super Sport.
Citing a more potent version of the GT-R's twin-turbocharged V-6 along with a healthy drop in weight, AutoExpress says that the performance is the result of the same group that helped develop the Juke Nismo, Williams Advanced Engineering. An unnamed engineer for Williams (it's not made clear if this is the same source from Goodwood) notes that there are improvements to be had "even with a car like the GT-R."
As exciting as the GT-R Nismo is going to be, we're having a hard time accepting that it will be able to hit 60 in two seconds flat, at least on street tires. What do you think? Have your say in Comments.

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.

Recharge Wrap-up: Shift to offer Teslas for Hire, Model S P85D beats Ferrari in drag race

A company called Shift plans to provide bikes and EVs for hire. Based in Las Vegas, NV, Shift will provide chauffeured ride services like Uber, but will also include a car- and bike-sharing service that delivers the desired wheels to the customer. Shift's fleet will include EVs like the Smart Fortwo Electric Drive and the Tesla Model S. Shift also promises that you will, "Be on your way within five minutes," which is a pretty tall order. Shift is scheduled to be available to members beginning this fall. Read more at The Car Connection. Nissan UK has confirmed the price of replacement batteries for the Leaf. UK drivers will be able to buy new batteries for 4,920 pounds (or about $7,738). That's considerably more than the price of $5,499 for US customers. Customers get 1,000 pounds back when they exchange their old battery. The original battery is covered under a five-year, 60,000-mile warranty, and most owners will never need to replace it. According to Nissan, only three replacement batteries have been sold out of 30,000 Leafs sold in Europe. Read more at Autocar. The Tesla Model S P85D walloped a Ferrari in an impromptu drag race video. The Ferrari driver pulls up alongside the Tesla and asks, "What you got in there?" before challenging him to a race. The Ferrari gets a head start, but the Tesla pulls out ahead quickly. The video also gets the reactions of some passengers to the car's mighty acceleration. See the video below and read the account of a drag race against a Lamborghini Aventador at Car Throttle. Australian website Drive has chosen their Cars of the Year in various categories. The Tesla Model S was a carryover winner for Luxury Car Over $80,000, but the Mercedes-Benz C200 narrowly overtook it to be crowned the overall winner. Regarding the Model S, one judge says, "This makes every other EV look at least a generation behind." The main thing that held the Tesla back from winning outright was the near-term lack of charging infrastructure. The judges did note Tesla's plans to build a network of Superchargers in Australia, but also pointed out that those plans exclude much of the country so far.
