Nissan withdraws from two races to focus on Le Mans

Nissan is making a huge bet and putting all of its chips on the 24 Hours of Le Mans for the race debut of the GT-R LM Nismo. The team will now skip the World Endurance Championship test at Paul Ricard in France later this month and also won't compete at the first two races of the season at Silverstone and Spa-Francorchamps. The team made the announcement through two tweets (embedded below). "Our main aim for this year was always Le Mans and we have decided to re-focus on that race," Darren Cox, Nissan Motorsport boss, said to Autosport. In the meantime, the company will keep testing the car in the US right up until the big race. The driver lineup and a GT-R Nismo for display will make an appearance at the season-opening round at Silverstone on April 12, though, according to Autosport. This isn't the first setback for the team. The GT-R LM suffered a failure of a "very minor" part during testing in early March at Sebring, and the team didn't have a spare with it. The car had run 68 laps over the preceding two days. The GT-R LM uses a powertrain unlike any other vehicle in its class. A twin-turbocharged V6 has front-mid-engine placement, and it's combined with electric motors making over 700 horsepower. In total, the system generates a claimed output of over 1,250 horsepower. With no competitive racing under its belt before Le Mans, the Nissan is definitely going to be a car to watch in the big event this year. This content is hosted by a third party.

2015 Nissan Murano and Juke priced, Color Studio to breed bad ideas

Nissan has released basic pricing information on its upcoming Murano, as well as detailed pricing on the refreshed Juke crossover at the 2014 LA Auto Show. The Japanese company also announced a new "color studio" for the Juke, which just reeks of bad ideas. First, let's talk money. The flashy, redesigned Murano crossover will kick off at $29,650, not including an $885 destination charge. While the new CUV will begin arriving in dealers on December 5, Nissan opted out of providing more detailed pricing data, including information about trim levels and other optional extras. It did no such thing with the Juke, though. The freshened 2015 model starts at $20,250 for a base Juke S, and climbs from there. The SV trim adds $1,050 to the price while the SL starts at $25,240. All-wheel drive adds $1,850 to the S and SV models and $1,700 to SL. If you're the sporting sort, the Juke Nismo starts at $24,830 while the Nismo RS rings up at $28,020. Adding an Xtronic continuously variable transmission and all-wheel-drive to the Nismo models increases the price by $2,400 and $2,000, respectively. And now, the Nissan Color Studio. We'll admit, there are some among the Autoblog staff that question this new feature, which gives customers an extreme degree of control when it comes to the styling of their Juke. For a price, Nissan will allow customers to choose individual colors for ten different parts of the Juke, including the rear spoiler, mirror caps, headlight surrounds, door sills and the wheels. While a fashionable mind might be able to create something rather cool, the potential for abuse here is extremely high. Check out the inset image to see what we mean. Scroll down for Nissan's announcement on Juke and Murano pricing, as well as details on the color studio.

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.
