Mitsubishi Motors to relocate North America HQ to Tennessee

NASHVILLE, Tenn. — Mitsubishi Motors announced on Tuesday that it is relocating its North America headquarters from California to Tennessee, a move that will bring the Japanese automaker closer to its sister company Nissan and strengthen Tennessee's growing reputation as an epicenter of the automotive sector. Tennessee Gov. Bill Lee and Department of Economic and Community Development Commissioner Bob Rolfe — who made the announcement with Mitsubishi Motors North America — say the headquarters move from Cypress, California, to Franklin, Tennessee, will result in an $18.25 million investment in the region and approximately 200 jobs. Lee and Rolfe added that they met with Mitsubishi's global executives last week to convince them to move to Tennessee while in Japan during the Republican governor's first trade mission. It is unclear what financial incentives state officials offered Mitsubishi to move to Tennessee. "As we drive toward the future, this is the perfect time for us to move to a new home. While we say farewell to the Golden State with a heavy heart, we're excited to say hello to Music City," Fred Diaz, Mitsubishi Motors North America's president and CEO, said in a statement. Franklin is located just south of Nashville, also known as "Music City," and is home to the state's most powerful Republicans, ranging from Gov. Lee, U.S. Sen. Marsha Blackburn and House Speaker Glen Casada. "Over the years, Tennessee has become the epicenter of the Southeast's thriving automotive sector, and I'm proud Mitsubishi Motors will call Franklin its U.S. home and bring 200 high-quality jobs to Middle Tennessee," Lee, who took over the office this year, said in a statement. Mitsubishi Motors' North America headquarters has been located in California since 1988. The company expects the relocation will begin in August and will be completed by the end of the year. Initially, a temporary office will handle operations to allow the company time to identify a permanent office. Company officials say the move is part an ongoing effort to "reinvent every aspect of Mitsubishi Motors in the U.S.," as well as strengthen the Renault-Nissan-Mitsubishi Alliance. Nissan has a production plant in Smyrna, Tennessee, and owns a 34% stake in Mitsubishi Motors. Last week, Mitsubishi Motors Corp.

Preserving automotive history costs big bucks

$1.8 million is spent each year to maintain GM's fleet of 600 production and concept cars.
When at least two of the Detroit Three were on the verge of death a few years back, one of the tough questions that was asked of Ford, General Motors and Chrysler execs - outside of why execs were still taking private planes to meetings - was why each company maintained huge archives of old production and concept vehicles. GM, for example, had an 1,100-vehicle collection when talk of a federal bailout began.

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.
