37K miles in a 1967 Datsun Roadster

When we think of comfy, long-distance road cars, there are a few obvious choices. A Mercedes-Benz S-Class, Bentley Continental GT or, assuming fuel efficiency isn't paramount, a Range Rover are all good options for a road trip. But what if that road trip was 37,000 miles? Maybe something more reliable but still comfortable, then, like a Honda Accord. What about a 1967 Datsun Roadster?
As insane as it sounds, Scott Fisher is doing just that, running a Datsun 1600 Roadster across North America and racking up 13,500 miles in his first three months on the road. His total journey will see him pile over 37,000 miles on his red convertible. The car is lightly modified, but most of the work is for the sake of reliability and comfort, with a five-speed manual 'box, an upgraded radiator and electronic ignition.
Fisher's trip hasn't been all smooth, with a few typical bits of trouble. He also ran into some deer in Utah, quite literally, clipping one of the animals, which delivered quite a bit of damage to the passenger's front fender (hence the rear three-quarter view in our lead shot). Still, the car seems to be holding up well, as shown in this latest video from Petrolicious.

Ghosn: 'While I'm proud of our EV leadership, I know it's not enough.'

Renault-Nissan CEO Carlos Ghosn has written something like a State of the Union on electric vehicles and the carbon economy. We'd sum it up as, 'we're working on it but we all need to work harder.' Ghosn believes all of the commitments made at the Paris COP21 climate change conference are a start, but "the support of the business community is imperative," in coordination with the public sector. He stresses that he's after an "orderly transition," one that uses what we have now in order to go where many believe we need to go. That means no threats or revolution, no "aggressive government intervention and centralized demand and control," but rather a "practical, affordable way to begin reducing dependence" on the fuel that turns the skies brown. Ghosn wraps up his manifesto this way: "The UN Secretary General recently said that we are the first generation to feel the effects of climate change and the last to be able to do anything to stop it. This is a call to action, and the auto industry is committed to doing its part." Based on the undeniable shift toward the electrification of the automobile, we know that the call is being answered. Given the limited market share EVs have today, it could still use some more people and companies picking up the phone. With vehicle numbers expected to grow from 800 million to more than two billion by 2050, "transition will occur one way or another," Ghosn writes. Head over to Forbes to read Ghosn's thoughts.

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.
