BMW unleashes new M4 racer on DTM

We may not get to enjoy the fruits of it all, but we're in the midst of a golden age in touring car racing around the world. In Northern Europe, rival local series have amalgamated into the Scandinavian Touring Car Championship. In the UK, the British Touring Car Championship is enjoying the largest and most diverse grid in its long history. In Australia, the V8 Supercars series has grown from a Holden vs. Ford battle to include challengers from Mercedes, Nissan and Volvo. And in Germany, the DTM championship has managed to lure BMW back onto the grid to open up the battle between Mercedes and Audi. All good things, in short.
Since returning to the Deutsche Tourenwagen Masters in 2012, BMW has won the drivers' title once and the constructors' title twice, proving the Bavarian manufacturer to be not only a suitable challenger to the two-horse race between its star- and ring-emblazoned rivals, but the dominant force in German tin-top racing. Now BMW is set to enter its third season since returning to the DTM, and this is the car with which it intends to do so.
Replacing the M3 DTM that has impressively won half of the DTM races it has contested over the past two years, BMW's latest racing car is made in the mold of the new M4 coupe. Only it's even meaner. While the production version has switched to a turbo six, the DTM version still uses a V8: a 4.0-liter unit with four-valve cylinder heads, mandatory air restrictors and a Bosch ECU to channel 480 horsepower and 369 pound-feet of torque to the rear set of Hankook racing slicks through a six-speed sequential gearbox. The lightweight chassis is rounded out with competition-level aerodynamics and all the mandatory safety equipment.

Of course, AC Schnitzer's buyers also want to show off their cars' added performance, and the company is ready with a host of carbon fiber pieces.

The troubled Alfa Romeo Giulia needs serious help [UPDATE]

UPDATE: An Alfa Romeo US spokesman responded to this article with the following statement: The safety concerns expressed in the story are false. The all-new 2017 Alfa Romeo Giulia is designed and engineered to meet or exceed all federal safety regulations. The Alfa Romeo Giulia will begin production for the North American market in the late second-quarter of this year. Alfa Romeo will have a full product portfolio of premium vehicles that includes plans for (8) all-new Alfa Romeo vehicles by 2020. The product launches are prioritized by segment volumes starting this year with the Alfa Romeo Giulia production for North America starting in late Q2, followed by the Midsize-UV – the 2nd largest premium segment in North America. Even on the day you dragged them kicking and screaming and gesticulating wildly to a table full of concrete evidence, Alfa Romeo executives will never admit the Giulia program is going through a tough patch. But it is. Reports say the Giulia, on the eve of production, didn't just fail one internal crash test, but failed the front, side and rear impact tests. Alfa denies it. Automotive News published a report last week saying two suppliers had insisted the Giulia, on the eve of production, didn't just fail one internal crash test, but failed the front-, side-, and rear-impact tests. A third supplier source told us the same thing. Alfa is denying it. It was due on sale in Europe late last year and was supposed to be here in the next month or two. But it wasn't, and it won't. It was to be headlined by a twin-turbo V6 that reportedly howled its way around the Nurburgring 14 seconds faster than the BMW M3 could manage. That second part is only true if you believe it's fair to compare a full lap in a standard BMW M3 with a favorable accumulation of sector times to a development prototype Giulia with 220 pounds stripped out of it and rolling on hand-cut racing slicks. No, me neither. A Promising Start The Giulia's all-new architecture was developed in just two years by a skunkworks of young engineers headed by Fiat's engineering prince, Philippe Krief, and (bafflingly) sited inside Maserati's headquarters complex in Modena, about three hours from Alfa Romeo's own Turin HQ.
