2016 Chevrolet Spark gleams in green in New York

Take one look at the 2016 Chevrolet Spark that's debuting at the 2015 New York Auto Show, and you can immediately see that the little hatchback is growing up. The previous long headlights and tall greenhouse are gone in favor of a slightly more conventional look that suits the enlarged overall size well. To address complaints about a lack of power from the current Spark's 1.2-liter engine, the latest model gets a larger 1.4-liter unit making 98 horsepower. It can be paired with a five-speed manual transmission, but for those looking to maximize fuel economy, a CVT offers an estimated 40 miles per gallon highway fuel economy. Beyond the new engine, there's an upgraded platform underneath with a longer wheelbase. The underpinnings are also more rigid, as well, to help improve handling and lower interior noise. Inside, the Spark now gets some physical controls to go along with the seven-inch MyLink infotainment system. A rearview camera is standard, which seems almost unnecessary is such compact model, and buyers can further enhance safety with tech like a Forward Collision Alert, Lane Departure Warning and Side Blind Spot Alert. Check out the gallery above to see the Spark in its nuclear green paint at the New York show before the little hatch arrives at dealers in the fourth quarter of 2015.

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.

Chevrolet Captiva looks mildly refreshed and ready for family duty

We showed you Chevrolet's major debut yesterday, the 2014 Corvette Stingray Convertible, but General Motors is making a big push for Bowtie consideration in Europe, so it's also introducing the updated Captiva crossover here at the Geneva Motor Show.
While still based on the same platform as North America's fleet-only Captiva Sport (which is effectively a rebadged Saturn Vue), the Captiva is available in both five- and seven-seat iterations, and it looks far more modern. That's particularly the case with this updated model, which features revamped front- and rear ends that include restyled bumpers, grilles and LED taillamps, among other changes.
As before, the midsize Theta-platform CUV will be available in both front- and all-wheel drive, and is expected to carry a range of four- and six-cylinder gasoline and diesel engines. Important US programming note: Chevrolet sources tell us that America's Captiva Sport will not receive these updates.
