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.

BMW sees shortage of crossovers in the United States

BMW of North America CEO Ludwig Willisch is anxious to get the Bavarian brand's $1-billion upgrade at the Spartanburg, SC, factory done because the automaker can't keep up with demand for its crossovers. The expansion should boost total capacity there to 450,000 units a year and support production of the upcoming X7. Still, Willisch would love to have more crossovers as soon as possible. "That is a constant battle now, to get more X3s and X5s," he said in an interview about the company's future in North America to Automotive News. If they the supply were available, Willisch predicts he could sell at least another 10,000 of the CUVs. Willisch sees getting the X7 on the market as a big win for the brand, too. "We were able to convince the company that this is exactly what we need in the United States," he said to Automotive News. However, there is a bit of a wait. The model rides on BMW's next-gen platform, and is at least two years away from challenging the Land Rover Range Rover and Mercedes-Benz's renamed GLS-Class (previously the GL-Class). The fullsize CUV reportedly shares development with Rolls-Royce and might offer the best interior of any model bearing the blue and white roundel. The boss also talked about other future product plans for this continent. For example, Willisch reiterated BMW will not bring the 2 Series hatchbacks here, citing a lack of a market for them. There will be plenty more plug-in hybrids available at dealers, though. Due to "legal requirements" and popularity, Willlisch says PHEV versions will be offered throughout the lineup by 2017. Although, the i sub-brand will stick with the i3 and i8 through that time.

All 25 James Bond movies ranked only by their cars

There is no shortage of lists ranking the best James Bond movies. Ditto lists about the best or worst James Bond cars. I know, I've written some of them. As such, why not combine the two ideas into one new list that ranks all 25 official James Bond movies based exclusively on their cars, or more accurately their car content. I would then pull from my 25 years of James Bond nerddom plus the excellent "Bond Cars: The Definitive History" and our interview with long-time Bond special effects supervisor Chris Corbould to provide tidbits and factoids about the cars and their roles in the movies. And yes(!), this list now includes "No Time to Die," which impresses by adding plenty of car content to the series. It's now available on Blu-ray and download. To determine the list, I considered the inherent coolness of the cars as well as their importance to Bond, film and car history. I considered their importance to the story as well as the quality/excitement of the chases and scenes they participated in. Finally, I tried my best to divorce the car content from my opinions about the movies in general. That my personal list of best James movies looks nothing like this shows I was at least partially successful.     25. 'Moonraker' There are virtually no cars in "Moonraker." None. Oh, there's a gondola on wheels that makes a pigeon do a double-take, but that's not the same thing as a car. Neither is a golf cart. Or an ambulance. Or a space shuttle.   24. 'From Russia With Love' The literary James Bond mostly drove an ancient Bentley, and "From Russia with Love" is the only film in which it appears. It stays parked and the coolest thing that happens (by 1962 standards) is 007 answers its car phone. Thereafter, we get some old cars (even by 1962 standards) driving around Istanbul and a yellow truck. So yeah. Classic Bond film, a must-watch, just not for its car content.   23. 'Dr. No' History records that the first "Bond car" is the Sunbeam Alpine in "Dr. No." The car itself was literally borrowed from a Miss Jennifer Jackson of 53 Lady Musgrave Road in Jamaica for 10 pounds per day for two days during filming. Also, the stunt where it drove under an excavator blocking the road was entirely conceived because the filmmakers showed up to the road they intended to film on and discovered an excavator blocking the thing. Sadly, those are really the only two things interesting about the Alpine, which is a pretty small and dainty thing by Bond car standards.
