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.

Gary Cooper's 1935 Duesenberg SSJ fetches record price at Pebble Beach

The 1935 Duesenberg SSJ formerly owned by Gary Cooper sold for a jaw-dropping $22 million over the weekend at the Gooding & Co. Pebble Beach auction, setting a record for the most valuable pre-war car ever sold at auction. It also appears to have become the most expensive American collector car ever sold at auction, eclipsing the very first Shelby Cobra ever made, which sold for $13.75 million in 2016. The Duesenberg was also the lone American-made entrant in the list of top 10 sellers, which was crowded with the names Ferrari and Porsche. You have to go all the way down the list to No. 21 to find the next American car: a 1930 Packard 734 Speedster Phaeton, which sold for a mere $1.127 million. All told, Gooding & Co. said it realized more than $116.5 million in auction sales over the weekend, with a whopping 25 cars sold for north of $1 million, an 84 percent sales rate and an average transaction price of $947,174. Clearly this is how the other half 1 percent lives. Gooding & Co. said there were five world-record sales at the auction. Joining the Duesenberg were a 1955 Ferrari 500 Mondial Series II, which sold for $5.005 million; a 1958 Ferrari 250 GT Tour de France Berlinetta, $6.6 million; a 1967 Ferrari 330 GTC Speciale, $3.41 million; and a one-of-two 1966 Ferrari Dino Berlinetta GT, $3.08 million. Oh, and that 1969 Ford Bronco test vehicle we told you about? The one that was rebadged by Holman & Moody as a Bronco Hunter? It sold for $121,000, which was well below the expected range of $180,000 to $220,000. Perhaps it was the presence of all those gorgeous Porsche Spyders and Ferraris that meant collectors weren't interested in boxy, utilitarian off-roaders. View 24 Photos Gooding and Co. had expected the convertible Duesenberg coupe to go for more than $10 million. It was one of only two of its kind built by Duesenberg — the other having gone to Clark Gable — with a specially shortened, 125-inch wheelbase and a supercharged straight-eight with double overhead cams, able to produce around 400 horsepower and a top speed of 140 miles per hour. It features a lightweight open-roadster bobtail body produced by LaGrande out of Connersville, Ind. The car was also owned at one point by race driver Briggs Cunningham.

Mercedes S63 AMG Coupe vs Porsche Panamera Turbo S in unusual lux showdown

We'll admit it, we're really looking forward to more time with the Mercedes-Benz S-Class Coupe. Compared to other high-dollar luxury coupes - we're looking at you Bentley Continental GT - it's more stylish, easily more affordable, and since it's a Mercedes, lacks the sense of fragility that comes with a more exotic name plate.
Auto Express has taken a whack at reviewing the new two-door S-Class, and for some reason, the British mag is comparing it with a Porsche Panamera. Now, while comparing the looks of an S-Class Coupe and a Panamera is a bit like holding a beauty contest between Kate Upton and Medusa, this isn't as bizarre a pair as you might think, particularly when you opt for the high-dollar S63 AMG Coupe and the Panamera Turbo S.
The two offer similar power outputs from their force-induced V8s - 577 horsepower in the Benz and 570 horsepower in the Porsche - and are even similar in terms of interior and exterior dimensions. The S-Class actually has an extra inch between the axles and is 1.2 inches longer overall (it's also about 300 pounds heavier). In the cabin, the S-Class also has a tiny bit more rear legroom, with 33.4 inches to the Panamera's 33.3.
