Tesla exec calls rival EVs 'little more than appliances'

Tesla's Vice President of Business Development Diarmuid O'Connell called the company's competition "little more than appliances" at the Center for Automotive Research's Management Briefing Seminars in Traverse City, MI yesterday. "In essence, [mainstream automakers] delivered little more than appliances," O' Connell said. "Now, appliances are useful. But they tend to be white. They tend to be unemotional." According to Automotive News, O'Connell's main critique is that vehicles like the Nissan Leaf and BMW i3 don't deliver enough performance or range to draw the attention of consumers outside of a small group. The solution, in O'Connell's mind, is more power, more range, more excitement and a lower price – that last point is particularly rich coming from an automaker whose cheapest current offering, the Model S 60, costs $66,000 – although the cheaper Model 3 is on the horizon, way out there, somewhere. But some EVs are better than none, O'Connell added. "On balance, I'm happier that [traditional automakers are] doing these cars than not," O'Connell said. "I just wish they would do them better and faster." O'Connell also used his appearance at the Management Briefing Seminars to launch a volley at the Michigan legislature, blaming its opposition to Tesla's direct-sales model for the lack of available EVs in the Wolverine State. "I think if the Michigan Legislature would allow Tesla to sell cars in Michigan, we could probably address [the lack of available electric cars]," O'Connell said. Related Video:

Nissan to run two GT-R GT3 cars in 2015 Pirelli World Challenge series

Nissan will be lining up two FIA GT3-spec GT-Rs on the start line of the 2015 Pirelli World Challenge at the Circuit of the Americas March 6-8. Sponsored by Always Evolving, Replay XD cameras, and Nismo, the two entrants will be driven by American GT Academy winner Bryan Heitkotter and Australian racer James Davison. AIM Motorsport, the Canadian race shop founded by Roger Rodas and Erik Davis, will handle preparation of the car. It will be the first time the GT3 GT-R has come to race in America. It will race in a highly varied field, with Audi, Ferrari, Dodge, and Aston Martin among the series runners. Check out the press release below for more details. NISSAN ANNOUNCES PARTNERSHIP WITH ALWAYS EVOLVING TO CAMPAIGN TWO NISSAN GT-R GT3 CARS FOR 2015 PIRELLI WORLD CHALLENGE - 2011 Nissan GT Academy Champion Bryan Heitkotter to pilot #05 GT-R GT3 - IndyCar, Prototype and GT racer James Davison to Campaign #33 GT-R GT3 - First U.S. Appearance of Nissan GT-R Built to FIA GT3 Specifications - Debuts in Pirelli World Challenge at Circuit of the Americas March 6-8 NASHVILLE, Tenn. 19/02/15 – Nissan Motorsports announced today a partnership with Always Evolving (AE) to campaign two GT Academy-NISMO Nissan GT-R GT3 racing cars for the 2015 Pirelli World Challenge season. Nissan GT Academy North America 2011 winner Bryan Heitkotter will drive one of the team cars, while Australian open wheel and GT star James Davison will pilot the second car. Featuring logos from the GT Academy program, the two cars will be co-sponsored by Replay XD and NISMO. AE will utilize AIM Autosport for much of the car preparation and on-track support during the season. Based in Los Angeles, the team was founded in March 2013 by friends Roger Rodas and Erik Davis as a platform combine their passion for cars and their desire to support their favorite charitable organizations. Following Rodas' tragic passing in November 2013, the team has established "Racing in Honor" as their internal mission for the 2014 season in his memory. AIM won the 2012 IMSA GTD team, driver and manufacturer championships, as well as the 2013 manufacturer title while campaigning a Ferrari. "Nissan couldn't be happier to have Always Evolving and AIM as Nissan's partners to campaign the first GT3 spec GT-Rs in the U.S. in Pirelli World Challenge," said Rick Kulach, Nissan North America Motorsports Manager.

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.
