Nissan looking to expand UK plant to build Infiniti Q30

With the Infiniti Q30 concept heading to the Frankfurt Motor Show next month and a future premium compact model heading into production at Nissan's Sunderland UK assembly plant, just connecting the dots tells us this new small Infiniti is headed for UK production. Backing this up, Reuters is reporting that Nissan is looking to expand the Sunderland plant by 25,000 square feet, while Automotive News Europe takes it a step further by almost confirming that the Q30 will be built alongside the Nissan Qashqai and Note.
The reports say that Sunderland is already the UK's biggest automotive plant, but the expansion will make it even larger with production capacity expected to rise from the current 500,000 units built each year to more than 550,000. There is no indication if the expansion will bring more jobs to the plant, which already employs around 6,000 people.

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.

St. Louis man charged in killing of Illinois college student

A St. Louis man has been arrested and charged with murder in the slaying of a 19-year-old Illinois college student who went missing while trying to sell his sports car on Craigslist, authorities said. Capt. Tim Fagan of the Florissant, Missouri, police department said at a news conference Wednesday night that 24-year-old Michael Gordon was taken into custody Tuesday and was being held at the St. Louis County jail in lieu of $1 million bond. Gordon has been charged with first-degree murder and armed criminal action in the death of Taylor Clark, a sophomore engineering student at Southern Illinois University-Edwardsville. Fagan, the deputy commander of the Major Case Squad of Greater St. Louis and lead investigator in the case, said police arrested Gordon after his name was found in emails Gordon traded with Clark about the car Clark was trying to sell. Investigators said the two did not know one another before they met. Police say Gordon is an employee of a truck driver training center in the St. Louis suburb of Hazelwood, Missouri, not far from where Clark's 2007 Nissan 350ZX and body were found Tuesday. It was not immediately clear whether Gordon has an attorney. Clark, who is from the southwestern Illinois town of St. Jacob, was reported missing by family members on Monday. Authorities say he was last seen by his girlfriend. "Our hearts and minds are with Taylor Clark's family and friends as they cope with this tragic loss," SIU-E Chancellor Julie Furst-Bowe said in a statement issued Wednesday. "At a time of the year when the new spring season brings the promise of brighter days ahead, and commencement provides unending potential for so many of our students, it is truly sad that Taylor had his bright future taken away." The Belleville (Illinois) News-Democrat reported that Clark worked at a convenience store in Troy, where a candlelight vigil was scheduled for Wednesday night. A similar vigil was held Tuesday night on campus. Clark's death comes during the same week as a Monday court hearing in St. Charles County in which a 23-year-old man was sentenced to life in prison for fatally stabbing a 45-year-old St. Louis man during an encounter and planned robbery in 2012 that was set up through a Craigslist ad. On the same day of the hearing, Fairview Heights, Illinois, police unveiled a "safe exchange zone" on its parking lot, complete with security cameras, to help citizens safely broker online transactions with strangers.
