2013 BMW M3 Coupe Lime Rock Park Edition

Sic Transit Gloria
I like difficult cars. I like turbo "moments," dramatic weight distribution, low-grip, peaky power delivery, and overly quick steering, along with ultra-short wheelbases and any number of other non-racecar-perfect dynamic foibles. I love the newest generation of BMW cars and engines - all turbo'd up with tons of torque and power everywhere in the rev range, too. But what I think the enthusiast community will miss when this 2013 M3 Coupe becomes the 2014 M4 Coupe - replacing its idiosyncratic, small-displacement, revvy V8 for something like a triple-turbo, directly injected, inline six-cylinder powerhouse in the process - is the work it takes to drive the car fast and perfectly. Sometimes small flaws just make things better; my mistress' eyes are nothing like the sun, and all that.
The idea of this E92 M3 going away then, magnified by the loss of the M3 badge for the coupe, is at best bittersweet for me. This generation of M car is already surpassed in terms of raw thrills by the better-than-ever Mercedes-Benz C63, a car that doesn't ask its driver to sacrifice low-end grunt or the very latest in amenities in return for stellar backroad performance. Yet any time I've been lucky enough to lap a track in the M3, it has quickly become clear that the Bimmer is the better on-edge tool. With the freedom to wring the neck of the 4.0-liter V8 and room to exercise the lovely balance of the car, the E92 is hard to match (even six years after its debut).

Lexus to use BMW 3.0-liter straight-six in next-gen IS sedan?

Here's a rumor so wild it needs a U.S. Fish and Wildlife permit. Japan's Best Car magazine reports that the next-generation Lexus IS will offer BMW's B58 3.0-liter inline-six as one of four powertrain options. That's the same engine found in the new Toyota Supra with 335 horsepower and 365 pound-feet of torque. What's more, the fourth-gen IS will resurrect the IS F model gone AWOL during the current third generation, and do it with the twin-turbo V6 from the Lexus LS 500. The current TTV6 makes the same 416 hp in the LS 500 as the 5.0-liter V8 did in the first Lexus IS F 12 years ago. According to the magazine, the other engine options would be Toyota's 2.0-liter turbocharged four-cylinder, a 2.5-liter for a hybrid model, and a 2.4-liter turbo. We don't know where that last engine fits in. BMW doesn't make a 2.4-liter, and Toyota appears to have retired all of its 2.4-liter applications. Ignoring that, the 3.0-liter straight-six looks like it would replace the current 3.5-liter V6 rated at 311 hp and 280 lb-ft. This wouldn't be the first time the Supra's engine has been ported to the IS. Lexus mavens will remember that two years after the introduction of the original IS in 1998, Lexus put the Supra's 2JZ 3.0-liter straight-six engine in the IS 300 — without the turbochargers, thank you. But Best Car's prediction would have zero relation to history. Those were both Toyota engines back in 2000, and even ignoring the power differential, the IS didn't compete with the Supra. Putting BMW's 3.0-liter in the Z4 and the Supra works because they are the same car. And again, even ignoring the power differential, the more powerful Z4 doesn't compete with the Supra. Best Car's scenario has BMW selling one of its best engines for use in a direct competitor to the 3 Series. Lexus would need to design an engine bay long enough to swallow an inline-six, not a bread-and-butter engine for the brand, yet still be sensible for three more compact powerplants. Then, assuming BMW and Toyota made the same deal as with the Z4 and Supra, the Lexus would be down by a healthy double-digit horsepower margin on its German foe. The new Supra gives up 47 hp to the roadster. Where's the upside? It's said the trim sedan will stay about the same size, on a wheelbase roughly four centimeters longer, but lose a substantial chunk of weight.

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.
