2014 BMW Z4 sDrive35is

The BMW Z3/Z4 roadster has never really had a widespread following because it has either been too humble and small a roadster (albeit with some fun and very low-volume M editions) or it has been - in this E89 generation - too casual an image leader with no racier aspirations. The current 480-hp Z4 GTEs don't count, since they are as stock a Z4 as today's Pamela Anderson is the same blonde actress we knew as Heidi on Home Improvement. You know, sort of like those ever-so-slightly modified Toyota Camry coupes competing in NASCAR.
The ultimate highpoint for the BMW Z roadster franchise was at the very start of its life in the mid-90s, in the James Bond film GoldenEye with Pierce Brosnan. The Stinger missiles that Q's team installed behind the Z3's headlights were never fired, and BMW never even offered this self-defense package as an option. Yet another case of the ol' bait and switch.
And in all these subsequent years of Z3s and Z4s strutting their long-hooded stuff, the little sporting Bimmer could really have used a live Stinger missile or two to spice things up. The current Z4 exists, it is pretty dang sexy, and BMW seems content to let it linger there. We just drove the new midlife version of the roadster near BMW headquarters in Munich, and it served to reinforce our feelings.

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.

BMW reminds us what made the original M3 so great

Just because many are slavering for the global debut of the 2016 BMW M2 at the Detroit Motor Show doesn't mean BMW will let us forget the coupe that gave the letter "M" its global moxie: the M3. The Roundel has posted the first in a five-part series devoted to that seminal M, the 1987-1991 E30. Built as a homologation requirement for the race car BMW needed to beat Mercedes 190E 2.3/16V in the German Touring Car Championship, it was 1.5 times more expensive than the 325i of the time and company sales heads had doubts about being able to sell all 5,000 of them. As we know, that story had a happy ending. The first models came with a 2.3-liter four-cylinder with 195 horsepower, a chopped and tuned combination of the four-cylinder M10 block first used in 1962 and in Formula 1, with a cylinder head from the six-cylinder M88 that did duty in the M1. By the time the M3 Sport Evolution models marked the end of the first-gen production run, displacement had risen to 2.5 literz and output to 238 hp, but more important than those numbers were the phenomenal handling and relentless race victories. You should definitely check out the video above for BMW's peek into the backstory of the fourth M car after the M1, M535i, M635 CSi, and M5, and arguably most important. But if your M-centric tastebuds prefer a more modern take on the German brand's most driver-friendly vehicles, take a look at the videos below. Related Video:
