Nissan GT-R takes a bloody whack at supercar rivals in fake ads

A big part of what makes a supercar super is how it makes you feel, but the performance stats and bragging rights are undeniably a big part of the equation as well. Which means you can't ignore the fact that, even with its price ever escalating, the Nissan GT-R makes minced meat out of European exotics costing twice or three times as much.
That's the inspiration for this trio of fake ads from photographer Tim Kent. In this mock campaign, Kent has depicted the GT-R as a butcher's knife and the European exotics as pieces of slaughtered meat. Ferrari is symbolized by a package of horse meat, Porsche by a pack of sausages and Lamborghini as a pair of, um... "prairie oysters".
Of course the ads are never going to run anywhere, and if you're squeamish (or vegetarian) we wouldn't suggest looking at them in close proximity to your lunch. But we have to admit they're creative, and effective.

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.

Dacia Duster to spawn inexpensive Nissan Terrano, will we get it?

When going to overseas auto shows, one can't help but spend an inordinate amount of time eyeballing forbidden automotive fruit. It's often of the seriously rare, criminally powerful and six- or seven-digit variety. But more often than one might think, the genuinely affordable overseas hero makes us swoon, too. So it is with the Dacia/Renault Duster, the cheap-as-chips, hard-wearing utility vehicle. We've often thought that its basic, rugged charms would play well in the US if saddled with a low enough price tag, but we've never seen much of a window for that to actually come true.
But now, Autocar India is reporting that Nissan will flex its alliance with Renault to spin off a Duster of its own, one that exhumes the Terrano nameplate, a moniker once used for overseas versions of the first- and second-generation Pathfinder. The new model will feature unique sheetmetal to give it a familial look, but the interior will be the same, and we expect the same goes for the powertrain, meaning there will be a range of gasoline and diesel four-cylinder engines with both manual and automatic gearboxes and front- or all-wheel drive.
So, does that mean we'll get a Nissan version of the Duster-based Terrano to call our own? Sadly, almost certainly not. Company spokesman Dan Bedore tells Autoblog flatly, "There are no plans to bring this model to the US." Bummer. Even if it isn't ultimately as capable as the larger, long-in-the-tooth Xterra (it's more on par with the now departed Canadian-market X-Trail), we think the Duster's archetypal SUV looks and low cost barrier would win it plenty of fans in our market. Our guess is that redesigning the model to meet US regulations (crash, emissions, lighting, etc.) would be prohibitively expensive, and the Dacia/Renault model is built in some pretty distant facilities - Brazil, India, Romania and Russia among them - making the business case harder still.
