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.

Veneno Roadster, One:1, One-77, LaFerrari, P1, Veyron headline 25-car Bonham's auction

Bonhams is holding a no-reserve auction in fall 2019 that includes some of the most valuable and sought-after supercars of the past decade. The lot of 25 beautiful collector items includes a Lamborghini Veneno Roadster, a Koenigsegg One:1, an Aston Martin One-77, a Ferrari LaFerrari, a McLaren P1, and a Bugatti Veyron. The collection, which was seized from a corrupt politician from Equatorial Guinea, is valued at roughly $13 million. If selling off future classics that are still in their infancy as collector items seems strange, it's because this is not a straightforward situation. These cars will be sold off by the State of Geneva, not a person. The collection was previously owned by the vice president of Equatorial Guinea, Teodoro Obiang, but the cars were seized when he was placed under investigation for money laundering and unfair management of public interests. These 25 cars, which were located in Geneva, were first sequestered in fall 2016. A trial court ordered them sold off, and the money earned from the sales would be invested in social programs that benefit Equatorial Guinea. And so, Equatorial Guinea is about to see an influx of cash, as every vehicle is valued in the hundreds of thousands, if not millions, of dollars. The rarest might be the Koenigsegg One:1. One of only six remaining, it has 371 miles on the dial, and is valued at roughly $1.8 million. The Lamborghini Veneno Roadster, one of nine in the world, is a close second. It has 202 miles logged, and is valued at about $5.1 million. The Aston Martin One-77 is another rare bird. It is example No. 35 of 77, holds a 7.3-liter V12 engine, and is valued at about $1.4 million. A McLaren P1, Ferrari LaFerrari, and Bugatti Veyron 16.4 round out the top of the list. The remaining cars are not fully detailed, but they include examples from Mercedes-Maybach, Bentley, Maserati and Porsche. The auction will take place on Sunday, Sept. 29, at the Bonmont Golf & Country Club near Lake Geneva. For more photos and information, visit Bonhams.

NHTSA, IIHS, and 20 automakers to make auto braking standard by 2022

The National Highway Traffic Safety Administration, the Insurance Institute for Highway Safety and virtually every automaker in the US domestic market have announced a pact to make automatic emergency braking standard by 2022. Here's the full rundown of companies involved: BMW, Fiat Chrysler Automobiles, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Subaru, Tesla, Toyota, Volkswagen, and Volvo (not to mention the brands that fall under each automaker's respective umbrella). Like we reported yesterday, AEB will be as ubiquitous in the future as traction and stability control are today. But the thing to note here is that this is not a governmental mandate. It's truly an agreement between automakers and the government, a fact that NHTSA claims will lead to widespread adoption three years sooner than a formal rule. That fact in itself should prevent up to 28,000 crashes and 12,000 injuries. The agreement will come into effect in two waves. For the majority of vehicles on the road – those with gross vehicle weights below 8,500 pounds – AEB will need to be standard equipment by September 1, 2022. Vehicles between 8,501 and 10,000 pounds will have an extra three years to offer AEB. "It's an exciting time for vehicle safety. By proactively making emergency braking systems standard equipment on their vehicles, these 20 automakers will help prevent thousands of crashes and save lives," said Secretary of Transportation Anthony Foxx said in an official statement. "It's a win for safety and a win for consumers." Read on for the official press release from NHTSA.

Automakers making the commitment are Audi, BMW, FCA US LLC, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Maserati, Mazda, Mercedes-Benz, Mitsubishi Motors, Nissan, Porsche, Subaru, Tesla Motors Inc., Toyota, Volkswagen and Volvo Car USA.
