Watch Nissan prank unsuspecting test drivers with GT Academy

Nissan's reality show/motorsports program, GT Academy, is set to return to Spike TV for its fourth season on Friday, and in anticipation, the Nismo team has issued a new video that gives some of its fans a taste of the racing lifestyle.
It all starts innocently enough, with fans test-driving a 2015 Nissan 370Z Nismo, only to have a sudden stop quickly transforms things into something a bit more exuberant and special. We won't spoil the details, so take a look at the video for yourself, and then head into Comments and let us know what you think.
GT Academy will air on Spike TV, Friday nights at 11:30 PM Eastern.

Renault plans to sail — literally, sail — on new class of cargo ship

Going green on the ocean may take another step toward reality in about two years, when Renault is expected to load automobiles aboard wind-powered ships for delivery around the world. The partnership between the car maker and Neoline, a French-based company, aims to reduce Renault’s global carbon footprint by eliminating many of the emissions from traditional fuel-powered cargo ships. Neoline officials said that, when propelled solely by the wind, their sailing ships' total emissions drop by as much as 90 percent. The roll-on-roll-off ships will use solid sails that are 50 meters tall. The company says it will start testing the program in 2024 by transporting vehicles to North America and other locales from Saint-Nazaire, in western France. Renault has pledged to achieve zero carbon in Europe by 2030 and worldwide by 2050. Renault, now part of an alliance with Nissan and Mitsubishi, hasnÂ’t sold cars in the U.S. market under its own brand name since 1987. A U.S. return as been considered for years, and the partners are now in talks that could reshape the alliance. The shipper's intent to deliver vehicles to North America is an intriguing wrinkle to those talks. The firm says that about 300 to 400 vehicles can be shipped on each Neoline vessel, although the loading will take longer that it would using a traditional cargo ship. A demonstration vessel shown was 446 feet in total length and had more than 45,000 square feet of sail. The partnership between Renault and Neoline was first announced in 2018.   Green Mitsubishi Nissan Green Culture

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.
