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.

Car designer Frank Stephenson wants to show you something ... smaller

Influential car designer Frank Stephenson has often thought small. Now he’s thinking smaller. Throughout the past three decades, he has shaped — literally — some of the most indelible designs in automotive history: the modern Mini, the Ferrari FXX track star, the Maserati Gran Sport, a range of stunning McLarens and down to the funky 21st-century version of the Fiat 500. Now heÂ’s turned his pen to fashioning watches. His Cosmos analog piece, made to mirror “a black hole in space” and detailed “with an orange pinstripe which simulates the supernova glow of a neutron star,” features a Japan-built quartz movement and was created in concert with the Time Concepts company. “ItÂ’s the age-old adage ‘car people are watch people,Â’ so it was a natural step for me to get creative with timepieces too,” Stephenson said in a statement. “The collection showcases the love I have for exceptional and emotionally charged design, just like what is required in designing world class cars.” While Stephenson, who is 64, may be best known publicly for his vision of “affordable style” with the Mini and the Fiat, his ethos also translated to the utilitarian. In the case of BMW in the mid-1990s, the company was hustling to market an SUV, and turned to him for inspiration. His team had six months to complete the project. The result was the high-end X5, which Stephenson sketched during a two-hour flight. In 2018, Stephenson established the independent design company, Frank Stephenson Design, based in London.
