Nissan demonstrates GT-R LM Nismo's radical aero

Nissan took a radical approach in designing its GT-R LM Nismo, turning the usual LMP1 form on its head to create a rather unusual prototype. So why did it take such a drastic approach? In a word: aero. In designing a front-engined, front-drive Le Mans prototype, Nissan was able to free itself from many of the restrictions placed on aerodynamic development. So while the likes of Toyota, Audi and Porsche struggle to create as much downforce as the regulations will allow at the rear of their cars, Nissan is finding boatloads more at the front. It's an innovative approach if we've ever seen one, and you can see and hear the team explain how it all works in this latest video clip above.

Nissan alters all CVTs to act less like a stretched rubberband

Among automotive enthusiasts, no one seems to hold a neutral opinion when it comes to continuously variable transmissions. CVTs are either praised for their ability to boost fuel economy or chided for their occasionally poor driving dynamics. Nissan is among the masters of these un-shifting gearboxes in the US, and it uses them in many vehicles in its lineup. However, for the 2015 model year, several models are getting a software update to make their CVTs a bit more like a conventional automatic.
To give drivers the option of feeling gearshifts while on the road, Nissan is adding its D-Step Shift Logic feature to the CVTs in multiple vehicles. Steve Powers, Nissan's senior manager of powertrain performance, told Autoblog the system forces the transmission to "hold a ratio and then shift" to simulate the way that a traditional automatic would. It's simply a change in software, but the company "can't do it to older CVTs," he said, because it would require changes to transmission logic, as well. According to Automotive News, the upgrade is coming to the 2015 Versa, Versa Note (pictured above), Sentra, V6-equipped Altima, Pathfinder and Quest. "We're rolling it out to all programs," said Powers.
Interestingly, buyer perception appears to be pushing the upgrade. John Curl, a Nissan North America regional product manager, told Automotive News that the decision to add the tech partially comes because some owners are bothered that the CVTs aren't changing gears. According to Powers, D-Step "avoids the rubber band feel," that many drivers didn't like. The different sensation of these transmissions seems like something consumers would notice during the test drive, or that the salesperson would inform them about. The same issue cropped up last year when the company was facing customer satisfaction problems among new buyers customers' unfamiliarity with the gearboxes.

Runway Rumble: Nissan GT-R, Ducati 1098 and Lamborghini Reventon Roadster battle it out

One 2.5-mile runway, three different ways to take off: a Ducati 1098, a tuned Nissan GT-R with 580 horsepower and a launch control upgrade, and a Lamborghini Reventon Roadster. You'd naturally expect the Ducati to assert it's lightweight, high-horsepower authority in these matters, but with more than two miles to run, the ride that gets the jump at the line isn't always the one that gets the win.
That comes in especially handy for the Lamborghini, which suffers from a bad start in the first race and just looks plain ordinary in the second, until it finds redemption. You can see how it all goes down in the video below.
