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.

Buy a McLaren P1 GTR, Porsche 918 Spyder, and a Ferrari LaFerrari all in one place

The McLaren P1, Porsche 918 Spyder, and Ferrari LaFerrari, are arguably the three greatest hypercars yet. Of course, their extremely limited production meant that some ultra-wealthy individuals may have missed out on picking one up. In fact, to get a LaFerrari, you needed to have owned a certain number of Ferraris, and be in good graces with the company. However, if there are any super-rich car enthusiasts reading this right now, your chance to buy one or all of these three supercars is coming up next month at the RM Sotheby's Villa Erba auction in Italy. It will occur on May 27, and feature a McLaren P1 GTR, Porsche 918 Spyder Weissach, and Ferrari LaFerrari. 2016 McLaren P1 GTR McLaren fans, will RM Sotheby's won't offering just any McLaren P1, but rather the hardcore, track-prepped GTR variant. In fact, the GTR is so hardcore that it isn't legal for the street. This particular version went to specialist Lanzante to be converted for road use. Take note that it's only road legal in the UK, and it may not meet laws for other countries. However, that's still more than most GTRs can boast, and if you have the money for this, you shouldn't have any issue taking it to the UK to unleash the P1 GTR's 986 horsepower on public roads. This car could use some driving, too, as it only has about 223 miles on it, some of which included just one track event. RM Sotheby's expects this McLaren to go for between $3.4 million and $3.85 million. 2015 Porsche 918 Spyder Weissach View 31 Photos The Porsche 918 Spyder going up for auction is a special one as well. The first difference you'll notice is that it has been painted a custom color called "Arrow Blue," a hue specially mixed up as part of Porsche's custom paint service. It also features the lightweight Weissach package, which loses a few extra pounds by replacing an assortment of parts for lighter components. Among them are magnesium wheels and wheel bearings, carbon fiber roof, windshield frame, rear fenders, and rear view mirrors, and even titanium-backed brake pads. According to RM Sotheby's those pads have been replaced with fresh 918-spec pieces. The previous owner clearly enjoyed his or her 918, as it has just over 6,800 miles. In case you're interested in a well-loved 918, the auction house expects it to sell for just under $1.3 million to about $1.5 million.

Preserving automotive history costs big bucks

$1.8 million is spent each year to maintain GM's fleet of 600 production and concept cars.
When at least two of the Detroit Three were on the verge of death a few years back, one of the tough questions that was asked of Ford, General Motors and Chrysler execs - outside of why execs were still taking private planes to meetings - was why each company maintained huge archives of old production and concept vehicles. GM, for example, had an 1,100-vehicle collection when talk of a federal bailout began.
