Mercedes considering Mexico for CLA production

Would you buy a Mercedes-Benz if it were made in Mexico? That's what the German outfit is wondering, as it considers localizing production of the its new budget model at a factory operated by Nissan, of which the automaker is a joint-venture partner.
According to a report from Automotive News, moving production of American-spec CLAs from Hungary to Mexico would protect Mercedes from currency fluctuations. "Mexico is the best location for the United States," Daimler Chairman Dieter Zetsche told AN. The CLA is also expected to become the brand's volume model in the US market, which makes North American production a logical move.
In the event that Mercedes approves the plan, Nissan would expand the capabilities at its Aguascalientes, Mexico plant, allowing production to begin in 2018.

Nissan expands US EV test market for e-NV200 to Portland

Of course, it's going to be Portland. Oregon's largest city, known for its green-friendly vibe and policies, will be where Nissan will next test of its all-electric e-NV200 cargo van. And we hope those vans have cup holders for the inevitable java. The Japanese automaker is working with local utility company Portland General Electric (PGE) on a six-week trial program. Nissan and PGE will record data to better measure how the concept of battery-powered driving works within the local services network. The location makes sense, as Portland is one of the five best-selling US cities when it comes to sales of the Nissan Leaf, which shares its powertrain with the e-NV200. Nissan kicked off its "No Charge to Charge" free-charging program for new Leaf owners in April. Nissan, which had already been testing the e-NV200 with FedEx in Germany, Japan and Singapore as of late last year, said at the Washington Auto Show in January that it would start testing the electric van in the Washington, DC, area. Nissan said at the time that it helped install about 570 fast-charging CHAdeMO chargers throughout the US since last year, including 200 in December alone. Check out Nissan's press release about the Portland project below. LEADING EV MARKET PORTLAND BECOMES TEST BED FOR NISSAN E-NV200 ELECTRIC COMMERCIAL VEHICLE PORTLAND, Ore. – Portland, already a top breeding ground for electric vehicle (EV) sales, is now the proving ground for Nissan's prototype electric commercial vehicle – the Nissan e-NV200. Nissan is working in collaboration with Portland General Electric (PGE) on a six-week trial to help determine the viability of an electric commercial vehicle in the U.S market. PGE has assigned the e-NV200 into its fleet of vehicles with an underground crew, replacing a larger, diesel-powered van. "Oregon has been a top five market for Nissan LEAF sales in the U.S. due to proactive policies at the state level to encourage EV adoption, as well as robust charging infrastructure championed by the state and others like PGE," said Toby Perry, Nissan's director of EV Marketing in the U.S. "If we determine that e-NV200 fits into the U.S. commercial vehicle market, we expect that Portland would be a leading driver for sales as well." This year, Nissan is deploying two e-NV200 prototypes with companies such as PGE and FedEx in top U.S EV markets including California, Georgia, Oregon and Washington, D.C.

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.
