Porsche bringing Macan S Diesel to US instead of 4-cylinder [w/poll]

When Porsche unveiled the new Macan at the LA Auto Show, it announced two powerplants for the US market, both of them twin-turbo V6s: the Macan S equipped with 340 horsepower from its 3.0-liter engine, and the Macan Turbo with 400 horses from 3.6 liters. But those aren't the only engines Porsche will offer in its new compact crossover. Porsche is also offering the Macan S Diesel overseas with 258 hp, and reports have since indicated that a pair of four-cylinder models on their way: a 2.0-liter turbo four with 280 hp and four-pot turbodiesel of the same capacity with an as-yet undisclosed output.
Now Car and Driver is reporting that while those four-cylinder engines won't be making the transatlantic voyage to our shores, Porsche will offer the aforementioned Macan S Diesel in North America beginning in early 2015, nearly a year after the gas V6 versions arrive.
The 3.0-liter turbodiesel V6 is based on the same engine found in the Cayenne Diesel and the Audi Q5 TDI on which the Macan is based. Of course, its 248 hp is substantially less than the 340 ponies in the Macan S, but its 413 pound-feet of torque outshines not only the 339 lb-ft in the Macan S but also the 406 lb-ft in the Macan Turbo. Acceleration times, however, suggest the Macan S Diesel is still slower, with a 6.3-second run to 62 mph than neither the Macan S (5.4 sec) or Macan Turbo (4.8). The good news is that the Macan S Diesel is tipped to undercut the price of both, dropping the oil-burning crossover's MSRP below that of the $49,900 starting price for the Macan S and the $49,600 for the base Cayenne. If that C/D prediction comes to pass, that will make it the Macan S Diesel most affordable Porsche sold.

More details on Lanzante's F1-engined Porsche 930 restomod

Not long after last year's Porsche Rennsport Reunion, we posted on Lanzante Engineering's restomod project with the original Porsche 911 Turbo. McLaren Formula One used TAG-branded Porsche engines for four years in the 1980s to win two constructor's and three driver's championships. McLaren sold 11 of those engines to Lanzante — nine of which have been raced, one with a win to its credit — and Lanzante is installing them into the original chassis of some 930s. PistonHeads stopped by the shop to find out more. By the end of its service in the MP4/3, the TAG-Porsche TTE P01 motor rang up 1,060 horsepower in qualifying and 960 hp in the race, revving to a 12,600-rpm redline. Porsche engine legend Hans Mezger had led the development, coaxing those numbers from just 1.5-liters of V6 aided by two large KKK turbos at a max of four bar. All that was fine for a time when F1 ran with unlimited testing and unlimited parts, but a modern owner doesn't want to pay five techs to live in his garage and keep his car running. Lanzante asked Cosworth to make the engine more drivable and reliable. Cosworth installed a new crankcase, adjusted the air-fuel mixture, and installed smaller turbos for quicker power delivery, decreasing max boost by 25 percent to three bar (43 psi). The redline has come down to 9,000 rpm, for final output figures of 503 hp and 310 pound-feet of torque. According to PistonHeads, power climbs a "steady incline to redline," and more than half the rev band delivers maximum torque. The 503-hp rating doesn't sound like much today, when a Mustang gets more than 700 hp. Yet the first 930 Turbos got 296 hp and 243 lb-ft from a 3.0-liter flat-six with one big KKK turbo. The most powerful 930 Flatnose worked up 330 hp and 347 lb-ft from a 3.3-liter flat-six. Lanzante's taken out a ton of weight, though. The TAG engine is already 220 pounds lighter than the 930's 3.3-liter; a new carbon fiber hood and engine cover, and aluminum door skins shed more pounds. The total package weighs roughly 2,430 pounds, which is more than 500 pounds lighter than the original Porsche Turbo. That includes the extra pieces needed to make an F1 engine power a passenger car. Lanzante had to swap in a 930 Flatnose front bumper, which replaces the fog lights for oil coolers. The team put radiators at the front of the car as part of a brand new water cooling system. The climate control is entirely electric, because F1 cars didn't come with HVAC.

Porsche close to fix for 911 GT3 engine fires

It looks like 2014 Porsche 911 GT3 drivers might actually get to drive their cars again soon. Reports of fires affecting the track-ready Germans first began about a month ago. Then, a few days later, the automaker confirmed two of the five alleged blazes and said owners shouldn't drive their cars until further notice. Porsche then went so far as to offer to pick up the GT3s and transport them to the nearest dealer until the problem was identified and a fix was found. Finally, there appears to be a repair.
"We know the reason and the problem-solving measures. We're testing them," said Porsche CEO Matthias Müller to Bloomberg. The technical fix will be released to owners shortly.
The recall affects all 785 GT3s that have been sold so far, but there have been no reported injuries caused by the fires. When it first announced the safety campaign, Porsche said: "Internal studies to determine the cause of the engine damage have not been completed yet."
