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.

Fastest cars in the world by top speed, 0-60 and quarter mile

A claim for the title of “Fastest Car in the World” might seem easy to settle. ItÂ’s actually anything but: Are we talking production cars, race cars or customized monsters? And what does “fastest” even mean? For years, car publications have tended to define “fastest” in terms of an unbeatable top speed. ThatÂ’s distinct from the “quickest” car in a Usain Bolt-style dash from the starting blocks, as with the familiar 0-60 mph metric. Professionals often focus on track lap times or elapsed time-to-distance, as with a drag racer thatÂ’s first to trip the beam of light at the end of a quarter-mile; or the 1,000-foot trip of nitromethane-powered NHRA Top Fuel and Funny Car dragsters. Something tells us, however, that you're not seeking out an answer of "Brittany Force rewriting the NHRA record books with a 3.659-second pass at a boggling 338.17 mph." For most barroom speed arguments, the focus is firmly on cars you can buy in showrooms, even if many are beyond the financial means of all but the wealthiest buyers and collectors. Here are some of the enduring sources of speed claims, counter-claims, tall tales and taunting dismissals that are the lifeblood of car enthusiasts – now with EVs adding an unexpected twist to these passionate pursuits.   Fastest from the blocks: 0-60 mph Thirty years ago, any car that could clock 60 mph in five seconds or less was considered extremely quick. Today, high-performance, gasoline-powered sedans and SUVs are routinely breaking below 4 seconds. As of today, the 2023 Dodge Challenger SRT Demon 170 crushes all with a 0-60 mph time of just 1.66 seconds. That's simply absurd, but keep in mind the Demon was engineered with the single-minded purpose of going fast in a straight line. It's also important to realize that direct comparisons are difficult, because not all of these times were accomplished with similar conditions (prepped surfaces, adjustments for elevation and so on). The moral here is to take these times with a tiny grain of salt. After the Dodge, the Rimac Nevera comes in with an officially recorded 0-60 mph time of just 1.74 seconds. EVs crowd the quickest list, with the Pininfarina Battista coming in a few hundredths slower (1.79 seconds) than the Nevera and the Lucid Air sapphire (1.89 seconds) right after that. Eventually, you arrive to the Tesla Model S Plaid, which has a claimed 1.99-second 0-60 mph time, though instrumented testing by Car and Driver shows it accomplishes the deed in 2.1 seconds.

A fix and buyback program for Audi V6 diesels may be on the way

While Volkswagen reached a settlement to buy back 2.0-liter diesel inline-fours with emissions defeat devices, the roughly 80,000 cars with 3.0-liter diesel V6s built by Audi have yet to be addressed. But a new report from Bloomberg indicates that a solution is near. The publication says that sources familiar with the situation say the company has a fix ready for the majority of the cars, and that the EPA and California Air Resources Board are ready to approve it. According to Bloomberg, this fix would involve a software update and would work for about 60,000 of the Audi A8, Q5, Q7, Porsche Cayenne, and VW Touareg models with the engine. The rest of the vehicles won't be fixable without major modification, so those would have to be purchased back from the owners. Bloomberg does point out that approval from the EPA and CARB are only one piece of the puzzle. The publication said that this deal has yet to be approved by owners of the cars and the Federal Trade Commission, both of which may demand that VW offer a buyback to all owners, even those whose cars can be fixed. The good news for owners of VW products with this engine, is that they should have some closure pretty soon. And owners that still like their diesel V6 can take solace that they might actually be able to get them fixed, as opposed to owners of the 2.0-liter diesels. VW offered buybacks to owners of all 475,000 cars with the turbo four-cylinders, or a fix when it's available. However, there have been no signs of an approved fix.
