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.

Would you pay $17 a month to give your older Ford connectivity?

When it was first introduced in 2007, there was nothing like the original Ford Sync system, since it allowed car owners to connect and use a portable device better than anything that came before it. And because it was a brought-in/tethered and software-based system, Sync leveraged a device's connectivity and was easily updated. It took competitors awhile to catch up: Toyota Entune wasn't available until 2011, and Chevy MyLink didn't roll out until 2012. But now Ford is the one playing catchup since it stuck with the brought-in strategy while most other automakers were quicker to add connectivity via an embedded cellular modem. Ford initially installed 2G/3G modems in its small fleet of electric and plug-in electric vehicles starting in 2012 so that owners could keep tabs on charging. Embedded connectivity came to Lincoln in 2014, and Ford began adding onboard 4G LTE via Sync Connect to select cars starting with the Escape in 2015. To get more cars connected more quickly, last week the automaker rolled out its FordPass SmartLink solution that plugs into the OBD port of 2010 to 2017 model year vehicles. This lets owners retroactively get onboard Wi-Fi, set up a "geo-fence" to keep tabs on a car's location, receive vehicle health reports and allows remote engine starting and door locking/unlocking using a smartphone app, among other features. But to connect older Ford vehicles will cost owners $16.99 a month for two years, not including installation. Ford throws in 1 GB of data or a 30-day trial, whichever comes first, after which owners have to add the vehicle to their Verizon shared data plan, which supplies connectivity for SmartLink, or establish a new account. (Disclosure: Autoblog is owned by Verizon.) By comparison, GM's 4G LTE data plans start at $10 a month for 200 MB and goes up to $30 for 3 GB, and owners can also add a car to an AT&T shared-data plan. But OnStar doesn't have a separate monthly subscription for the embedded modem or an installation charge, and standard features via the RemoteLink Mobile App are free for the first five years of ownership. FCA's Uconnect Access service also uses an embedded modem to provide similar telematics features for $20 per month following a free one-year trial, while a la carte in-car Wi-Fi is offered for $10 per day, $20 per week or $35 per month.

2016 Chevy Volt zaps into the Detroit Auto Show with big improvements [w/video]

If you need an example of how quickly the plug-in hybrid market is evolving, just take a quick glance at the 2016 Chevrolet Volt. For its freshly introduced new generation at the 2015 Detroit Auto Show, the sedan sports extra range, better efficiency and a host of other improvements to make the vehicle even easier to live with. A big portion of the model's improvements come from Chevy's second-gen Voltec propulsion system. The updated drive unit is 12 percent more efficient and sheds 100 pounds from the scales. The battery itself also drops 21 pounds, while growing in capacity to 18.3 kilowatt hours. It gives the Volt an electric range of up to 50 miles and offers a total driving distance of over 400 miles. In addition, the new 1.5-liter engine offers estimated 41 miles per gallon fuel economy (with no battery). The significant improvement in specs are certainly respectable, but the vast majority of buyers should notice the latest Volt's evolved styling first. Up front, there's a shiny new nose with a more modern take on Chevy's split grille. From there, the design slows back to a more svelte take rear with the original model's futuristic, square taillights not making the transition. Inside, Chevy simplifies the infotainment system and now offers seating for three in the back. Check it all out in the gallery, above, to see how far the latest model has come. Chevrolet Introduces All-New 2016 Volt New model features expressive, sleek design and delivers 50 miles of EV range DETROIT – Chevrolet today unveiled the all-new 2016 Volt electric car with extended range, showcasing a sleeker, sportier design that offers 50 miles of EV range, greater efficiency and stronger acceleration. The Volt's new, efficient propulsion system will offer a General Motors'-estimated total driving range of more than 400 miles and with regular charging, owners are expected to travel more than 1,000 miles on average between gas fill-ups. "The 2016 Chevrolet Volt provides our owners with a no-compromise electric driving experience," said Alan Batey, president of GM North America. "We believe our engineering prowess combined with data from thousands of customers allows us to deliver the most capable plug-in vehicle in the industry." The 2016 Chevrolet Volt's technology and range advancements are complemented by a design that blends sculpted, muscular proportions with aerodynamic efficiency, and an all-new interior with seating for five and improved functionality.
