2015 Nissan GT-R Nismo to pack 595 hp, lap N"urburgring in 7:08

With two major auto shows taking place this week on different sides of the globe, the amount of news being posted across the internet is reaching a fever pitch. Naturally, things happen, trigger fingers get itchy and stories get leaked, which is apparently how we came across this spate of premature pictures and information on the eagerly anticipated Nissan GT-R Nismo.
Packing 595 horsepower and 480 pound-feet of torque from its twin-turbocharged, 3.8-liter V6, the Nismo-fied GT-R should be a serious kick in the pants when run hard. The new power is thanks to a number of donor parts from the GT-R Nismo GT3 racecar, bits that include larger turbochargers, revised intake and exhaust systems and new ignition timing.
Thanks to the engine enhancements, and, we imagine, a few other tweaks to the chassis, brakes and aerodynamics that have yet to be published, the GT-R Nismo is said to blitz the Nürburgring in just 7:08, a mere 11 seconds slower than the $845,000 Porsche 918 Spyder. For a car that is rumored to cost well under a quarter of the price, that performance is just immense.

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.

Datsun's lackluster initial sales fall below Tata Nano

When Tata introduced the Nano back in 2008, everyone was amazed at how cheap it was. They called it a game changer, but no game was changed. In fact, it took Tata five years to sell the 250,000 units it had the capacity to build in a single year. As it turns out, even buyers in what economists call "developing markets" like India aren't necessarily interested in buying an ultra-cheap automobile. And now it appears that Nissan may be falling into the same trap.
A little over a year ago, Nissan revived its old moniker Datsun to serve as a budget brand - similar to what ally Renault did with Dacia. Its lineup (consisting of models like the Go hatchback, Go+ minivan, On-Do sedan and Mi-Do hatch) is largely based on old architecture, packaged with little more than basic equipment and sold at rock-bottom prices. But Bloomberg reports that, even in the brand's core markets like India and Indonesia, the new Datsuns haven't been selling.
According to local industry figures, Datsun has sold fewer than 10,000 units of its $5,100 Go hatchbacks in India since its introduction back in March. Maruti Suzuki, by comparison, sells twice that many of its similarly priced Alto hatchbacks every month. In fact, after peaking in April, Datsun only sold 607 units in India this past July, dipping 77 percent to drop below even the number of Nanos which Tata sold that month.
