New BBC Top Gear season is off to a great start

The past few years have been very demanding for Top Gear fans. The Jeremy Clarkson Top Gear got too big for itself, and the core quality of the series degraded as stunts and jokes gradually became more and more stale. Things came to a head with the Fracasgate, with Clarkson punching a producer in a very nice hotel in Yorkshire with a very nice brass plaque commemorating "The End of Clarkson's BBC Career". Fast forward to a year ago, when the BBC produced a new series of Top Gear, with famed breakfast show person and shouting enthusiast Chris Evans hosting. Laden with personnel and curiously lacking any direction, the first new season collapsed onto itself with Evans eventually quitting the entire shindig. After that, viewers received a new, Amazon-produced Clarkson-Hammond-May series called The Grand Tour, which was often brilliant and just as often hampered by writing as hackneyed as the last Clarkson years of Top Gear. Now the slate is clean. Evans is gone. The first Grand Tour season has aired. The BBC has had a good long time to re-evaluate its strategy. And the first episode of this season's Top Gear has aired in the UK - and will air March 12 on BBC America. Your first extended look at all new #TopGear, coming 5 March. See you there pic.twitter.com/lYoYOtrWxR — Top Gear (@BBC_TopGear) February 23, 2017 What an improvement! It seems like the producers have taken an ax to everything not strictly necessary for making a great car show, and they've left what is absolutely crucial. There are the three car guys, Matt LeBlanc, Chris Harris and Rory Reid. There is a new studio. There is a new track car. There is a celebrity, but it's not painful to watch. There are easy jokes, there are car jokes, there are Ronin jokes. Ronin jokes! It's as if Harris, by dissecting continuity errors in the 1998 film's BMW chase, is reaching out to us fans, saying he's one of us, and he did notice the wrong wheels when the black BMW falls from the bridge. (Other mistakes are wrong-colored tach needles, for instance.) The first car film is a quality Ferrari FXX K piece, with Harris enjoying one of the 40 built track-day specials on the bankings of Daytona. It's remarkable it was Harris who was allowed to drive the exclusive Ferrari, as the first "outsider" (in his words) to drive one; years ago Harris was one of the most vocal critics of Ferrari's practices, resulting in him getting banned from driving press Ferraris. But then again, this is a customer car.

More German automakers may be afoul of US emission standards

Volkswagen has plenty of smoke to share, and that may mean fire for other German automakers that make diesel vehicles, says Automotive News. Earlier this month, European Federation for Transport and Environment said that BMW, Daimler's Mercedes-Benz and General Motor's Opel division are among other automakers that may have equipped their vehicles' diesel engines with similar software as VW's. That software was found to reduce emissions while a car is being tested for emissions and shuts down emissions-control systems during normal use. The European environmental group used data from the International Council on Clean Transportation. Automotive News notes that the European environmental group put out its own report earlier this month, before the VW scandal broke loose, but the report was pretty much overlooked. Now, VW is under fire after it was discovered that 2.0-liter diesel engines in the VW Jetta and Golf, and Audi A3, may be programmed to game the emissions system. VW sold almost a half-million diesel vehicles in the US during the past six years. Both BMW and Mercedes-Benz told Automotive News that the issue that befell VW doesn't apply to their diesel vehicles. Earlier this week, Volkswagen admitted its car ran the sneaky software, while the US Environmental Protection Agency (EPA) has started a probe on the company. VW is setting aside more than $7 billion to pay for the alleged violations. Meanwhile, US taxpayers may have spent as much as $51 million a year to pay for subsidies related to VW's diesel vehicle sales in 2009 alone, according to the Los Angeles Times.

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.
