BMW dishes on 'lightweight' 2014 M4

BMW's M cars are not what we'd call featherweights. Sure, the big, bruising twin-turbocharged V8s deliver a lot of power, but the fact of the matter is that more weight often equates to less fun.
Which is why we're so excited over a recent sit-down the blokes at Top Gear had with BMW's product manager for small and medium cars, Matt Collins. The chat led to talk of the M3 Coupe replacing M4. Collins confirmed that, yes, the new M4 would be turbocharged. The new engine will also be a six-cylinder, which should make purists happy.
"What we'd like is more focus on lightweight engineering." -Matt Collins

Thermal imagery of BMW M4 DTM pit stop is red hot

A pit stop is a pit stop, right? The race car pulls in, the crew changes the tires, pumps in some fuel, maybe swaps out a busted body panel or squeegees the windshield, and off it goes for another heat. Only pit stops have become the focus of news lately for a number of reasons, whether it's because of mishaps (like the ones that prompted F1 to ban mid-race refueling), new time records (due largely to said ban) or interesting new ways to film the fast-paced action.
A few weeks ago we brought you footage of an IndyCar pit stop filmed from multiple angles courtesy of Google Glass. Now BMW has released a brief clip of one of its M4 DTM racers coming in for fresh rubber, all filmed by infrared camera. Its the kind of technology BMW uses to help optimize its German touring cars for competition, and now the Bavarian outfit has released some footage for fans to enjoy.
The resulting thermal imagery gives you an idea of how hot the car runs (and where the heat is emanating from), how warm they get the fresh rubber before they get it onto the car, and what kind of temperatures the pit crew is subjected to. Look closely enough in the 25-second video below and you'll even see the heat sputtering out of the exhaust pipes as the M4 downshifts into its pit box. (Just don't try adjusting your speakers, the clip is without audio.)

BMW M235i in circuit scrap with legendary E46 M3 CSL

Earlier this month, we brought you news that BMW's one-year wonder, the 2011 1 Series M Coupe, is actually trading for more money today than it did when new. That sort of short-term appreciation is a major rarity with modern production cars, but apparently it's not the only BMW enthusiast coupe to enjoy far-above-average residual values. The not-for-North America 2004 M3 CSL, itself a single-year offering, apparently also fits that description, as we've just learned from Auto Express.
The M3 CSL ruled overseas BMW showrooms a decade ago, with just 1,400 examples built. Based on the well-regarded E46 M3, the rare two-door was relieved of extraneous bits for improved track work and driver fidelity, coming in at around 240 fewer pounds than a garden-variety M3. With carbon-fiber-reinforced plastic bodywork, thinner glass and a lot less sound insulation, the CSL was one of the more raucous cars of its day. Like the 1M Coupe, it was also one of the more connected cars of the era, with a retuned suspension, quicker steering, and a bit more power than its brethren.
As Auto Express points out, a good used one commands about the same money as a brand-new 2014 M235i - the closest thing BMW makes to a 1M Coupe today - which makes this video track battle an interesting new-versus-used showdown. According to AE, a well-sorted used M3 CSL will run UK consumers anywhere between £30,000 and £35,000 - roughly $50,000 to $59,000 US. That's a massive premium over the $10k-17k British buyers can expect to shell out for a comparable standard M3, similar to the story that plays out for the 1M versus lesser 1 Series variants.
