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.

Geely and Renault joint venture will develop internal combustion and hybrid tech

China's Geely Automobile Holdings and French car maker Renault SA on Tuesday said they will invest up to 7 billion euros ($7.71 billion) in a new equally held joint venture to develop gasoline engines and hybrid technology for automobiles. The JV is aimed at manufacturing more efficient internal combustion engines and hybrid systems at a time when the focus of much of the automobile industry has been on the capital-intensive transition to purely electric vehicles. "We are pleased to be embarking on this journey to become a global leader in hybrid technologies, providing low-emission solutions for automakers around the world," said Eric Li, Geely Holding Group chairman. The new company will employ 19,000 people at 17 engine plants and five research and development hubs, Renault said. At launch, it is expected to supply to multiple industrial customers including Volvo, Proton, Nissan, Mitsubishi Motors, and PUNCH Torino. The JV aims to have an annual production capacity of up to five million internal combustion, hybrid and plug-in hybrid engines and transmissions, Renault added. Reuters reported in March that the new venture will see 15 billion euros ($16.53 billion) in annual revenue. Saudi Aramco, which signed a letter of intent with Renault and Geely in March, is evaluating a strategic investment in the new company, Renault said. The Saudi oil producer has been involved in advanced discussions to take a stake of up to 20% in the JV, sources said earlier this year. Big oil firms have worked with automakers to develop sustainable fuels and hydrogen engines in recent years. But a deal here would make Aramco the first major oil producer to invest in the car business. The joint venture is expected to be launched in the second half of 2023.

Only 3 new cars cost under $20,000. Here’s what you should buy used instead

Looks like some more people have realized something we pointed out late last year. There are only three new cars under the magic $20,000 price limit currently for sale in the United States. Those three vehicles are the Nissan Versa with a starting price of $16,925 (all prices here include destination fee), the Kia Rio at $17,390 and the Mitsubishi Mirage at $17,650. Should push come to shove, so to speak, we'd probably pick the Nissan as our top choice among those three due to its practicality, comfort and overall polish when compared to its similarly priced peers. But really, as we've suggested before, there are better options. Our top pick for a used vehicle under $20,000 remains the Chevy Volt. It's stylish, comfortable, practical and, above all else, efficient, assuming you can plug it in at home. If you don't have access to a plug at home, you'll likely be able to find a very gently used car for the same price as one of the budget options above. We'd check out the Honda Fit, Kia Soul, Subaru Impreza, Toyota Corolla hatchback and Volkswagen Jetta from the  model years and aim for something with under 20,000 miles and with a year or two left of its factory warranty. A quick inventory search shows that some of those cars, notably the Impreza and Jetta, can even be found Certified Pre Owned in most parts of the country. For a more thorough breakdown of some of the available used-car options we'd recommend, check out our guide to the Best Cars Under $20,000. For what it's worth, with the average new car transaction price hovering alarmingly close to $50,000, we wouldn't expect to see any more options coming any time soon for well under half that sum.
