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.

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.

Nissan reveals updated 2015 370Z Nismo among the faithful

Well before quick Honda Si models of the '80s or the performance juggernaut that the Toyota Supra and Mazda RX-7 became in the 90s, the Datsun 240Z was an early stake in the ground for Japanese sports cars. It was affordable, but the original Z-car was also a capable coupe that could show its tail to European and American rivals. Today, Nissan celebrates the car each year with fellow enthusiasts at its ZDAYZ event, and this year in North Carolina, it's surprising fans by launching the 2015 370Z Nismo there with some significant upgrades.
The biggest change is that the 370Z Nismo is available with a seven-speed automatic transmission for the first time. The six-speed manual is still standard, of course. But for those who don't want to use a clutch, Nissan is offering the new automatic with Downshift Rev Matching and a manual mode via paddle shifters. Power is still provided by the same 3.7-liter V6 as last year, producing 350 horsepower and 276 pound-feet of torque with a limited-slip differential at the back for added traction.
This hottest 370Z model also receives a brand-new GT-R-inspired bodykit that features a deeper front fascia, LED running lights and blacked-out headlight bezels. It also sports a new chin spoiler bearing the Nismo emblem and red accents that flow from the front, down the side sills and all the way to the rear bumper. At the back, there is also a smaller ducktail spoiler for a more mature look. The 2015 also wears cool 19-inch forged aluminum wheels by Rays with a new twin-spoke design and charcoal finish. Compared to last year's model, it's a much more mature-looking coupe.
