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.

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.

November U.S. new car sales mixed as automakers deepen discounts

DETROIT — Major automakers posted mixed U.S. November new vehicle sales on Friday and predicted a competitive December as they rushed to sell vehicles and boost their numbers before 2017 ends. Automakers are trying to sell down 2017 model-year vehicles, offering high discounts to consumers as the year-end nears. In 2016, the industry reported record annual sales of 17.55 million units. According to consultancies J.D. Power and LMC, discounts have been above 10 percent of the average transaction price for 16 of the past 17 months, a level experts say is unhealthy and unsustainable. The November sales results come as the National Automobile Dealers Association said on Friday it expects new vehicle sales to decline to 16.7 million units in 2018, after dropping to 17.1 million for the full year in 2017. If that forecast comes true, the race to move new vehicles off dealers' lots will only intensify next year. Brandon Mason, a director at PwC's automotive practice, said a worrying trend for the industry was a rising number of subprime loans. He said subprime levels are at just over 20 percent of originations, against more than 30 percent prior to the Great Recession, but recent increases remain a concern. "That's a bit of a red flag," Mason said. "It's something to keep an eye on as we move into 2018." November results by automaker: General Motors: Sales fell 2.9 percent, with sales to consumers flat against the same month in 2016. Much of the decrease was driven by lower fleet sales. GM said strong SUV and crossover sales pushed its average transaction price for the month above $37,000 for the first time. The level of unsold cars, which has been a concern for analysts and the industry, rose slightly to 83 days' supply, from 80 days at the end of October. "More vehicles are sold in December than any other month, and we are very well positioned because we have momentum in so many segments, but especially in crossovers," said Kurt McNeil, U.S. vice president of sales operations. Fiat Chrysler Automobiles: Fleet sales are low-margin, and FCA in particular has targeted a significant reduction in this type of sale in 2017. It posted a 4 percent overall decrease in sales for November, but fleet sales were down 25 percent while sales to consumers were up 2 percent on the year. Ford: The No. 2 U.S. automaker reported a 6.7 percent increase for the month, with fleet sales up nearly 26 percent and retail sales 1.3 percent higher than in November 2016.
