Feds Probe Nissan Cars For Unintended Acceleration

DETROIT (AP) - The U.S. government's road safety agency is investigating complaints that a trim panel can cause unwanted acceleration in Nissan Versa small cars. The probe covers about 360,000 Nissan Versa and Versa Note subcompacts from the 2012 through 2014 model years. The National Highway Traffic Safety Administration says in documents posted Saturday on its website that four drivers have complained that a trim panel near the gas pedal can trap the edge of a driver's shoe. This can stop the driver from releasing the gas pedal quickly and delay braking. There are no reports of crashes or injuries, although one driver complained of a close call at an intersection on June 9. As the driver accelerated to make a left turn, a plastic trim panel that covers the center console trapped the driver's shoe and stopped it from moving off the gas pedal, the complaint said. "I used my right hand to grab my leg and pulled harder, immediately braking hard, then backing my foot off the brake as I squealed and skidded around the corner, almost going over the curb and crashing," the driver wrote. The driver reported that the edge of the trim piece wasn't secured and trapped the sole of a leather work boot. Drivers who file complaints are not identified by NHTSA. Two of the four complaints were from drivers of rental cars, the agency said. A fifth complaint was filed in an unidentified foreign country, according to NHTSA. Investigations can lead to recalls but so far there are none in this case. Messages were left seeking comment Saturday from a Nissan spokesman.

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.
