Rob Parsons, paraplegic, can drift better than you

"When something happens, you deal with it, and you move on. You don't dwell on something you can't control." Those are positive words coming from anybody. But it's particularly inspiring when the speaker is Rob Parsons. He was a competitor and later an event judge in the Dsport series until a dirt bike crash took Parson's ability to walk. He didn't let that get in the way of custom building a drift car that works with hand controls. And now that it works, he's plans to use his car to help other who share his automotive passion but can't operate pedals. The vehicle itself is based around a 1991 Nissan 180SX chassis with a 5.7-liter supercharged LS1 V8 under the hood, according to his website. To make the machine drivable for people without the use of their legs, Parsons made a hand control setup, and he claims to be faster now than years ago. This story of fighting past the seeming insurmountable challenges is truly heartwarming, and it's amazing to watch Parsons at work. A warning: there is some brief, not-safe-for-work language early in the video.

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.

European new car sales drop nearly 8% in first half of 2019

PARIS — European car sales dropped 7.9% in June, led by bigger declines for Nissan, Volvo and Fiat Chrysler (FCA), according to industry data published on Wednesday. Registrations fell to 1.49 million cars last month from 1.62 million a year earlier across the European Union and EFTA countries, the Brussels-based Association of European Carmakers said in a statement. Calendar effects resulted in two fewer sales days in most markets, accentuating the decline. Registrations for the first half closed 3.1% lower, ACEA said. For European carmakers, weakening demand at home compounds the pressure from a sharper contraction in China and emerging markets that may yet bring more profit warnings. NissanÂ’s aging model lineup contributed to a 26.6% June sales slump while Volvo Cars, owned by ChinaÂ’s Geely, saw deliveries tumble 21.7%. Registrations also fell 13.5% last month at FCA, 10.1% at BMW, 9.6% at Volkswagen Group and 8.2% for both Mercedes parent Daimler and FranceÂ’s PSA Group. The Peugeot makerÂ’s domestic rival Renault suffered less, posting a 3.9% decline. By the Numbers BMW Chrysler Fiat Nissan Volkswagen Volvo Peugeot Renault
