2014 BMW Z4 offers minor refinements with a majorly orange wrapper

The redesigned BMW Z4 was rolled out onto the show floor at the Detroit Auto Show, with the example in question being an sDrive35is variant, with the just-less-than-screaming Hyper Orange Package. The exclusive colorway includes the metallic orange paintjob, as well as trim-specific seats, stitching and accents for the interior. More importantly, the 35is driveline means that you'll find a high-output version of the turbocharged 3.0-liter N54 engine, here outputting 335 horsepower and 332 pound-feet of torque, and a 7-speed DCT gearbox.
Two slightly less ferociously powered versions of the Z4 will be available for the new model year, too (both familiar). The Z4 sDrive35i is good for 300 hp and 300 lb-ft, while the still-potent sDrive28i features a 2.0-liter turbo four-cylinder making 240 hp and 260 lb-ft.

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.

TRANSLOGIC 147: CES 2014 Autonomous Vehicles

We head back to CES in Las Vegas to check on the progress of autonomous vehicles in 2014. We go hands-free on the highway with Audi, narrowly avoid a collision with Ford and hear all about BMW's drifting driverless car. But first we take a ride on Induct's self-driving Navia shuttle.
