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.

Chevy Colorado gets box delete option designed for upfitters

The Colorado, which marks the return of Chevrolet to the midsize truck segment, is receiving critical praise, and now it's time for the pickup to get to work. At the National Truck Equipment Association Work Truck Show in Indianapolis, IN, Chevy is unveiling a box delete option package for the model that allows businesses to custom tailor the Colorado to their needs. The choice to remove the bed is exclusively available on the Colorado Work Truck trim in the rear-wheel drive, extended cab model with a 305-horsepower, 3.6-liter V6 and six-speed automatic gearbox, and Chevy claims this is the only option of its type in the segment. Beyond the obvious loss of the rear, these trucks feature eight mounting points on the frame for upfitters to install any necessary modifications. They also get the Z82 trailering package and a locking differential. The versions with the box delete package carry a payload rating of 2,200 pounds an a gross vehicle weight rating of 6,001 pounds. "It's ideal for utility companies requiring service bodies, as well as landscapers and other businesses needing the utility of a flatbed," Ed Peper, US Vice President for General Motors Fleet and Commerical, said in the option's announcement. Further options with the package are limited to choosing a repositioned fuel filler for the upfitter to install and deleting the rear seat for extra interior capacity. The box delete becomes available in mid-April, and buyers get a $300 credit off the price of the Colorado when it's selected. Colorado 'Box Delete' Expands Options for Businesses Chevrolet package offers unique midsize pickup platform for alternative uses 2015-03-04 INDIANAPOLIS – With a box delete option, business owners and fleet managers can have it their way when it comes to customizing the back end of the 2015 Chevrolet Colorado. Chevrolet today announced availability of the package in mid-April. It is on display this week at the annual National Truck Equipment Association Work Truck Show in Indianapolis. It is the only such option offered in the midsize truck segment. "With the segment-leading efficiency and maneuverable size, the Colorado makes a great, flexible choice for urban businesses and fleets to make the most of a midsize truck," said Ed Peper, U.S. vice president, GM Fleet & Commercial.

Both Android Auto and Apple CarPlay slated for Chevrolet lineup

Long awaited, the race among automakers to keep drivers connected to their smartphones has officially entered a new era. Hyundai said Tuesday it would be the first manufacturer to put Google's Android Auto into a production car, the 2015 Hyundai Sonata sedan. Not to be outdone, General Motors said today it'd offer both Android Auto and Apple's CarPlay on several Chevrolet models set to hit dealerships this summer. By giving car buyers the choice between these rival phone-projection systems, Chevrolet hopes to quell concerns from prospective customers worried about the compatibility of their smartphones and vehicles. "It's about providing choice," said Alicia Boler-Davis, GM's senior vice president for global connected car consumer experience. "No two customers are alike, and we cannot expect a single solution that works for every driver in every situation." Across the industry, automakers are rushing to add both to their cars as a growing base of customers seek an array of connected features. Estimates from automotive technology research firm SBD indicate smartphone-integrated content is available in 36 percent of current vehicles, and the company expects that penetration rate will grow to 84 percent by 2025. For Chevrolet, the systems will be available on select 2016 iterations of the Cruze, Camaro, Volt, Spark and Malibu as early as next month, and appear on 14 Chevy models overall for the 2016 model year. They're available on all trim levels, but they only work with the company's MyLink infotainment package installed in the cars, and the first to hit showrooms will only work on the seven-inch touchscreen models. "CarPlay and Android Auto, these are things that are addressable to the broad market, and I think it makes a lot of sense for GM to put it into Chevys first," IHS Automotive senior analyst Mark Boyadjis said. Via physical connections, both Apple CarPlay and Android Auto allow users access to smartphone features like turn-by-turn directions, phone calls, voice-to-text messages and music streaming. Interfaces are similar to the ones found on the respective smartphones, but on the dashboard, they're redesigned for a simpler, in-car experience. Fonts are larger, for example, and easier to press on a touchscreen. CarPlay relies heavily on Siri so that drivers spend more time staring at the road instead of their touchscreen. That sounds good, at least in theory.
