Nissan GT-R and Ferrari 458 Speciale in track battle by Evo

Supercar slayer. That's what they call the Nissan GT-R. And in many ways it is, even though its price and performance over the years have risen to put it squarely in supercar territory of its own right.
In fact, as Evo magazine has been compiling a list of its fastest cars - using the Anglesey Circuit in Wales as its common ground - the GT-R has came out on top... that is, until Evo tested the Ferrari 458 Speciale. The two are about as different as you can get within the supercar segment: one has a turbo six up front driving all four wheels in a 2+2 configuration, the other a mid-engined, rear-drive V8 two-seater. In fact the only common ground you're likely to find between them comes down to their two doors and dual-clutch transmissions. Though they serve it up in different ways, both are class-leading performers.
We're looking forward to watching Evo populate its leaderboard with more entries like the McLaren 650S and more potent Nismo GT-R, but in the meantime the British enthusiast magazine, by popular demand, has released side-by-side in-car footage of both supercars putting their best lap forward around the seaside circuit.

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.

Nissan Resonance Concept gives glimpse of next Murano

The Nissan Resonance Concept has bowed at the 2013 Detroit Auto Show, giving the world a glimpse at the company's future design direction for crossovers. Specifically, the concept heralds what the next-generation Murano may look like once it touches down. Nissan has already confirmed the successor to the big crossover's throne will be produced in Mississippi for the first time. With a "floating" roof and dynamic head lamp arrays, the Resonance boasts a far more athletic appearance than the snub-nosed current generation. Inside, designers worked up a cockpit aimed at conveying what "the future of first-class space travel might be."
Nissan isn't saying what the upcoming Murano will have under the hood, but the Resonance boasts an all-wheel-drive hybrid powertrain with a small-displacement internal combustion engine and an electric motor. A lithium-ion battery delivers power while a CVT takes care of putting power to the wheels. Take a look at the full press release below for more information.
