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.

Trucks, SUVs drive U.S. October new vehicle sales

DETROIT — Major automakers posted mixed U.S. new vehicle sales in October on Wednesday, though America's love affair with high-margin pickup trucks and SUVs remained in full bloom as larger, pricier vehicles fared better than passenger cars. Auto industry publication WardsAuto put the seasonally-adjusted annualized rate (SAAR) for light vehicle sales in October at a robust level of 18 million units. But after a long boom cycle, carmakers are still ill-prepared for the slight decline in sales anticipated for full-year 2017 and have taken too few steps to trim production, said Doug Mehl, a partner in consultancy A.T. Kearney's automotive practice. "When you make a new vehicle, you have volume assumptions tagged to it, and who wants to be the guy who says, 'I'm going to make less of this really cool model'?" Mehl said. "But eventually the market is the reality, and it's going to force companies one way or other here." General Motors GM reported a sales drop of 2.2 percent for the month, with consumer sales down 6.6 percent. But sales of high-margin pickup trucks, sport utility vehicles and crossovers all rose. GM also cut its inventory of unsold vehicles — a source of concern for the market — slightly. The automaker has worked to reduce its volume of excess inventory, including through significant production shutdowns in the third quarter. GM had said its inventory would rise in October. "We are heading into the fourth quarter with good momentum, thanks to a strong U.S. economy and very strong pickup and crossover sales," said Kurt McNeil, GM vice president for U.S. sales operations. GM slightly reduced consumer discounts as a percentage of average transaction prices to 13.5 percent, from 13.7 percent in the third quarter. Industry experts believe consumer discounts above 10 percent of the average transaction price are unhealthy as they erode resale values and are unsustainable in the long term. Consultants J.D. Power and LMC said last week that based on preliminary October sales numbers, discounts have exceeded 10 percent in 15 of the past 16 months. Ford The U.S. auto industry posted record sales of 17.55 million vehicles in 2016. New sales received a strong boost in September as consumers replaced vehicles damaged in southeast Texas by Hurricane Harvey the previous month. Full-year 2017 sales are expected to be slightly lower than 2016.

Recharge Wrap-up: first Chevy Volt hits 200K miles, DriveNow launches in London with BMW i3 on deck

The first Chevrolet Volt has driven over 200,000 miles. According to the owner, Erick Belmer, the car, which he purchased on March 28, 2012, is "holding up flawlessly" with "no noticeable battery capacity loss." Belmer has a commute of about 220 miles per day, rotates his tires every 10,000 miles, and gets an oil change every 38,000 miles. Belmer still loves driving his "dream car" every day, and says it is "wonderfully engineered." Read more at Inside EVs. DriveNow has launched in London, and will include the BMW i3 as part of its carsharing fleet. Daimler shut down its Car2go operations there just six months ago. Currently, DriveNow members have access to the BMW 1 Series and Mini Countryman, but come spring of 2015, DriveNow, which is a joint venture between BMW and Sixt SE, will add 30 all-electric i3 EVs to its London service. DriveNow's rates for London are set at 39 pence per minute, with an hourly maximum cost of GBP20 (about 61 US cents and $31, respectively). The service currently operates in the boroughs of Islington, Haringey and Hackney, with hopes of expanded service in the near future. Read more at Hybrid Cars or at Reuters. FIA's Formula E electric racing championship series received the Autosport award for Pioneering and Innovation. The award ceremony was a black-tie event at the Grosvenor House Hotel in London. Formula E CEO Alejandro Agag accepted the award. "Many people in motorsport, when we started Formula E, didn't think we would make the first race," says Agag. "To announce we were doing a championship with cars that didn't then exist was a real challenge. But after that first race in Beijing, everything worked." Read more at Formula E's website. The Nissan Leaf has driven over a billion collective kilometers. That's more than 621.3 million miles. Nissan said in August that it expected to reach that mark by January, and it has done just that. To celebrate, Nissan Europe has created a video to thank its 147,000 Leaf drivers to bring the car to that substantial milestone in less than four years. Check out the video below.
