Ward's reveals annual 10 Best Engines list for 2013

Ward's Auto has released its annual 10 Best Engines award winners. The 2013 list covers the full width and breadth of the internal combustion spectrum, from a spate of efficient four-cylinders to the most powerful production V8 on the planet. As always, the entries must be available in a production vehicle in the first quarter of 2013 with an MSRP of less than $55,000. The supercharged 3.0-liter V6 from the Audi S5 held on for the fourth consecutive year, and BMW earned two spots on the list with its turbo 2.0-liter four-cylinder and turbo 3.0-liter inline-six.
Ford pulled in two awards for its 2.0-liter EcoBoost four-cylinder and and the supercharged 5.8-liter V8 from the Shelby GT500. Honda matched BMW and Ford with two wins of its own. Wards awarded the 2.4-liter four-cylinder from the Honda Accord Sport as well as the 3.5-liter V6 from the Honda Accord. Chrysler, General Motors and Subaru each garnered a spot on the list as well for the 3.6-liter V6 in the Ram 1500, the turbo 2.0-liter four-cylinder in the Cadillac ATS and the 2.0-liter four-cylinder the Subaru BRZ, respectively. You can read the full press release below for more information.

BMW readying competition pack for M5, M6

According to Car and Driver, citing a report in BMW Blog, BMW will be offering performance upgrades - likely called the Competition package - for its M5 and M6 models (including the convertible and Gran Coupe versions of the M6). Both cars will continue to be offered with the normal 560-horsepower, 4.4-liter twin-turbocharged V8 engines, but this new performance pack is expected to add an additional 15 hp to the mix.
No need to worry, however - the upgrades won't simply be limited to a small boost in power. These M5 and M6 models will reportedly get new wheels, black exhaust tips, a more direct steering ratio and reworked suspension geometry which will provide better overall handling. Top speed is said to remain governed at 190 miles per hour, but that these extra improvements will shave one-tenth of a second off the cars' 0-60 times.
No pricing information has been revealed as of this writing, though we imagine it'll likely come at a substantial cost over the current starting prices of the M5 and M6 ($90,200 and $108,350, respectively).

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.
