Watch a Group B Porsche 911 tear up the 'Ring in the snow

The Nurburgring is a motorsports fantasyland during the best weather, but it looks even more exciting when the snow starts to fall. While the course isn't open to the general public during the winter, this Porsche 911 SC RS rally car managed a lap of the snow-covered Grand Prix Circuit, sliding the whole way around. The 911 SC RS isn't as famous as Porsche racers like the 917, but it has an interesting story. Porsche's development of the 959 was slow in the '80s, and this coupe was the company's stopgap for Group B rallying. The SC RS used the 911 Turbo's wider body, suspension, and brakes, but the car had a naturally aspirated 3.0-liter flat-six to drive the rear wheels. It couldn't compete against all-wheel drive beasts like the Audi Quattro, but one managed third place in the 1985 Tour de Corse in France. The SC RS sounds great in this video, and it looks even better kicking up snow. There's so much accumulation that you can't tell which way the track goes, but driver Patrick Simon knows his way around. After watching this clip, we think the 'Ring should unleash a few more old rally cars on the track for a new racing series next winter.

Porsche announces plan to replace 911 GT3 engines

About a month back, we reported that Porsche was suspending delivery of its 911 GT3 due to reported incidents of the engine bursting into flames. A few days later, Porsche told owners of the new track-ready models not to drive their cars and had their local dealers pick up the cars in question. Just a couple of days ago, we reported that Porsche was working on a fix, and now we have the official details.
Following an internal investigation prompted by two such incidents, Porsche has confirmed that is has identified the problem as resulting "from a loosened screw joint on the connecting rod." The loose connecting rod, Porsche found, damaged the crankcase, which in turn resulted in oil leaking and then - in at least two cases - igniting.
Our source is unaware of Porsche being contacted by GT3 owners concerned about the impact of a replacement engine on their car's collectibility or resale value.

Mysterious Porsche 911 Cabriolet spied, could be GTS

While Porsche's designers can jokingly be accused of being some of the laziest in the industry due to the incremental changes to the 911's iconic design, no such charge can be leveled against the engineers and product planning folks. That's because it seems like each week arrives with news of a new variation of the marque's iconic rear-engined sports car. So, for this week, we've brought you images of what we think is the new 911 GTS Cabriolet, undergoing testing in a thawing winter wonderland.
Now, what is it that gives this 911 away, compared to standard convertible? Well, the big thing is the new offset, center-mounted exhausts. Borrowing a page from the last Volkswagen R32, these exhaust tips are unlike anything we've seen from Porsche. Only the GT3 wears center pipes, and unlike these spy photos, the twin pipes on the track-minded 911 are stacked neatly alongside each other. The other change spotted by our spies is the set of active-aerodynamic flaps in the front bumper, which can automatically channel air toward the brakes for increased cooling, or close off to reduce drag, as needed.
Those exhausts are a pretty big design detail, and so far as we can tell is the only differentiator between the other 911s in this car's posse. Our spies speculate that this could be a 911 Speedster, but point out that both the canvas roof and windshield remain unchanged - the rumored Speedster model would almost certainly feature a different roof assembly along with a steeply raked windshield.
