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.

Porsche 911 puts Turbos on its turbos

Distinct from the turbo-but-not-Turbo Porsche 911, the new high-performance models come to market with either 540 or 580 horsepower, depending on which version of the 3.8-liter, twin-turbocharged flat-six engine you choose. Both figures count as a 20-horsepower bump over the last Turbo/Turbo S, allowing both models to hit 60 in under three seconds – 2.9 and 2.7 seconds, respectively – and in the case of the S, on to a 200-plus-mph top speed. This capability will not come cheap, of course. Before so much as dipping a toe into Porsche's notoriously deep options catalog, the base Turbo will demand a $160,195 check. That's awfully spendy, and things don't improve as you climb up the range. The cabriolet adds $12,300 to that, while the S starts at $189,095. Going topless in the Turbo S will require $201,395. We had no trouble building a Turbo S Coupe up to $211,000 without adding some of the more obnoxious options, like the $1,720 leather air vents. Check out our live galleries of both the new 911 Turbo and the 911 Turbo S at the top of the page. Redefining fast: the new 2017 Porsche 911 Turbo and 911 Turbo S Top model of the 911 range offers more power, fresh design, and enhanced features ATLANTA, Nov. 30, 2015 /PRNewswire/ -- Porsche will be off to a powerful start in 2016 when the 2017 911 Turbo and 911 Turbo S make their debut at the North American International Auto Show in Detroit in January. The top-of-the-line 911 models will be available in both coupe and convertible body styles and are equipped with engines offering 20 horsepower more than before, a sharper design, and enhanced features. The 3.8 liter twin-turbo six-cylinder engine powering the 911 Turbo now develops 540 hp. The increase in horsepower is achieved through modified intake ports in the cylinder heads, new fuel injectors, and higher fuel pressure. The 911 Turbo S now makes 580 hp thanks to new turbochargers with larger impelle. In addition to a higher maximum torque (553 lb.-ft. in overboost compared to 523 lb.-ft. on the Turbo), the Turbo S also has a higher redline (7200 rpm instead of 7000). Porsche is still the only manufacturer to use turbochargers with variable turbine geometry in gasoline engines. The engines now also have a dynamic boost function, which improves throttle response during spirited driving. It maintains the boost pressure during load changes – i.e. when the accelerator pedal is briefly released.

World Car Awards finalists snub American-branded vehicles — except for Bronco

The list of World Car Awards has been whittled down to 10 finalists, but only one American brand — Ford — appears among the remaining nine carmakers for this yearÂ’s top award. The Bronco is there, and it also is balloted as a finalist in the design category. The other categories are performance car, urban car, electric vehicle and luxury model. Each category has five finalists except World Car, which has 10. One brand conspicuous by its absence in any category: Tesla. The winner in each is scheduled to be crowned March 27 at the New York International Auto Show in Manhattan. This year marks the 20th year of the World Car Awards and the partnership with the New York show. The selection process involves 100-plus automotive journalists from 29 countries who vote, as they review and test-drive the eligible vehicles for the 2024 awards. Their journey is captured virtually on World Car TV. If youÂ’re counting, the brands that appear most on the six finals lists are Mercedes-Benz (four times), BMW (also four), Hyundai (three), and Volvo (three). HereÂ’s the full listing. A video clip showing all of them is here: World Car -BYD Seal / Atto 4 -Ford Bronco -Hyundai Kona / Kona Electric -Hyundai Santa Fe -Kia EV9 -Mazda CX-90 -Subaru Crosstrek -Toyota Prius -Volkswagen ID.7 -Volvo EX30 World Car Design of the Year Ford Bronco Ferrari Purosangue Toyota Prius Volvo EX30 Zeekr X 2024 World Electric Vehicle BMW i5 Kia EV9 Mercedes-Benz EQE SUV Volkswagen ID.7 Volvo EX30 2024 World Luxury Car - BMW 5 Series / i5 - Lexus LM - Mercedes-Benz CLE - Mercedes-Benz E-Class - Mercedes-Benz EQE SUV 2024 World Urban Car  - Abarth 500e - BYD Dolphin - Lexus LBX - Suzuki Fronx - Volvo EX30 2024 World Performance Car - BMW M2 - BMW XM - Ferrari Purosangue - Hyundai Ioniq 5 N - Porsche Cayenne Turbo E-Hybrid
