Do we finally know which hybrid hypercar is fastest?

In order to properly compare and contrast the performance characteristics of competitive automobiles, a number of variables have to be sorted out. For instance, to diminish the human component, the same driver must be used for each lap, that driver has to be capable of wringing the maximum level of performance from each vehicle, and they should all be checked and prepared to make sure they are within manufacturer specs before hitting the track. Speaking of which, the conditions at the track – and, of course, it goes without saying that the cars have to be tested at the same location, on the same day – have to be as similar as possible. Naturally, arranging all of these variables is difficult, if not impossible, and that's especially true when the contenders are the Ferrari LaFerrari, McLaren P1, and Porsche 918 Spyder. As range-topping models from well-established performance players, these three hybrid hypercars are often lumped into the same category. But which one is fastest? Well, that's been a tough nut to crack, in part because the manufacturers themselves haven't always been willing to play along when it comes time to test these machines head-to-head-to-head. And so, with all that (probably unnecessary) preamble out of the way, we present to you the video above, in which this particular vehicular pedestal is toppled. All three cars are owned by a man named Paul Bailey, they were tested on the same day at the Silverstone circuit in England, and each had British Touring Car driver Mat Jackson at the helm. We're not going to spoil the results, other than to say that all three vehicles were incredibly fast and within spitting distance of one another at the finish line, as you would expect. Intriguingly, this video is said to be part one in a three-part series, so we have more Ferrari vs. McLaren vs. Porsche action to look forward to.

Overnight action from the 24 Hours of Le Mans

We won't go into a recap here, but there are still leading positions being fought for in all classes - it's so close that leads are changing when a car goes into the pits. We'll let the recap wait until the end of the race, so for now enjoy some shots from last night's action at the 24 Hours of Le Mans.

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.
