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.

Watch the Chevy Corvette dismiss its Euro rivals at the hands of a Brit magazine

European auto writers, especially the British, have a bit of a reputation for favoring their own domestic cars over foreign rivals in comparison tests. Just think about how many times you've heard Jeremy Clarkson deify the latest product of UK loins while denigrating an American rival as a hopeless "Yank Tank." However, we have to tip our hats to the folks at Autocar because in its latest video comparing the 2014 Corvette Stingray to the Porsche 911, Jaguar F-Type V8 S and Audi R8, it's actually given the Vette a fair shake.
Autocar has put the Stingray through a battery of tests against what it considers to be the three best sports cars on sale in Europe today. And while the tests that it has chosen are somewhat random and subjective, it has concluded that the C7 can stand up against its rivals, even irrespective of its price. It's one thing to hear about how great the Stingray is from American writers, but it's great to know that not all Brits think we've gone crazy for calling the new Chevrolet "exquisite."

Performance cars old and new are headed to auction at Las Vegas Grand Prix

Auction house RM Sotheby's is hosting a sale ahead of the 2023 Las Vegas Formula One Grand Prix, and most of the lots that will cross the block were designed with performance in mind. Whether you want a supercar or a Formula One car, there's a chance you'll find it in Sin City. One of the highlights from the sale in terms of rarity and price is the Mercedes-AMG Petronas W04 that Lewis Hamilton drove in the 2013 F1 season. Assigned chassis number F1W04-04, it's the team's last car powered by a naturally-aspirated V8 engine, and you're on the wrong track if you're thinking of the 4.0-liter unit that powers AMG's road cars. The engine in question is a 2.4-liter unit that develops 750 horsepower and is capable of revving to a screaming 18,000 rpm. The KERS system injects 80 additional horses into the driveline. Hamilton drove F1W04-04 in 14 of the 2013 season's 19 races, and he won that year's Hungarian Grand Prix in the car. RM Sotheby's notes that F1W04-04 is "the sole example to be sold outside of the Mercedes-Benz organization," which explains why it expects the car will sell for anywhere between $10 million and $15 million excluding the buyer's fee and a 2.5% import duty that applies to American residents. That's a lot of money, but modern Formula One cars rarely come up for sale. Several other cars are expected to sell above the $1 million mark, including a 1999 Mercedes-Benz CLK GTR ($8 million to $9 million), a 1988 Porsche 959 Komfort ($1,650,000 to $1,850,000), and a 1996 Bugatti EB110 Super Sport ($2,500,000 to $3,250,000). The 1990 Ferrari F40 GT (one of 21 units built) could bring up to $4 million. You can take home a rare, high-end classic even if you cap your budget at $1 million. How about a 1984 Lamborghini Countach 5000 S that was delivered new to Ralph Lauren and that has been in the hands of its second owner since 1986? RM expects the coupe will sell for up to $900,000. The auction house is also giving enthusiasts two distinctly different ways to spend a six-digit sum on a 30-something-year-old Mercedes-Benz. There's a 1990 190E 2.5-16 Evolution with about 3,400 original miles that could fetch up to $700,000. That's a lot to pay for a W201, but this isn't a run-of-the-mill Baby Benz: It's one of 502 examples built for homologation purposes. Alternatively, the 1989 560SEC AMG 6.0 Wide-Body could sell for up to $900,000. It's one of the most emblematic cars designed by AMG before it joined Mercedes-Benz.
