Porsche 911 comes out on top in 2021 J.D. Power dependability study

Published

on

2018 Lexus RX 350L

The Porsche 911 was ranked the most dependable vehicle in J.D. Power’s annual Vehicle Dependability Study for the U.S. market, taking the honor from the Lexus ES which was the top-ranked vehicle in last year’s study.

Porsche itself just missed out on the top brand ranking which this year went to Lexus. Last year the honor went to Genesis in the Korean brand’s first year in the study.

The annual study examines problems experienced during the past 12 months by original owners of vehicles bought new three years ago, which for the 2021 study means models that were new for the 2018 model year. More than 33,000 owners were surveyed in the study.

Brands as well as individual nameplates in popular segments are ranked by the number of problems experienced per 100 vehicles (PP100), with a lower score reflecting higher quality. The study covers 177 specific problems ranging from engine and transmission issues to vehicle exterior to infotainment user-friendliness. According to the researchers, the number of reported problems was about 10% lower than in last year’s study.

The industry average was a PP100 of 121, down from 134 the previous year. It is the lowest PP100 score since the study was first run 32 years ago, reflecting improving dependability.

When it comes to individual brands, Lexus, which tends to rank at the top, ranked highest with a PP100 of 81. Porsche was second with a score of 86 followed by Kia in third with 97. Kia is noted for being the best among mainstream brands.

At the other end of the spectrum, Land Rover came in last with a PP100 of 244. Jaguar and Alfa Romeo also ranked near the bottom.

But before you write off the brands at the bottom, note that many of the problems found are rather superfluous. For example, some of the most common problems were related to voice recognition, Bluetooth connectivity, and other infotainment-related features.

“If an owner can’t rely on a system to work as they expect, it is also considered a lack of dependability,” the researchers said.

We should also point out that Tesla was included in the study for the first time this year, receiving a PP100 of 176. This ranks the brand close to the bottom as well. However, Tesla isn’t officially counted since the brand doesn’t grant J.D. Power permission to survey the owners of its vehicles in 15 states. The ranking given to Tesla in this year’s study was calculated on a “robust” sample of surveys from owners in the remaining states.

2021 Ram 1500 TRX strapped to dyno, puts out 583 hp at the rear wheels

2021 Hennessey Mammoth 1000 1500 TRX

The 2021 Ram 1500 TRX boasts a factory-quoted 702 hp and 650 lb-ft of torque, but that’s as measured at the crank, not the wheels. Hennessey Performance Engineering tried to measure how much power the TRX makes at the wheels by strapping one to a dyno, but only ran numbers for the rear wheels.

The dyno test showed 538 hp and 570 lb-ft of torque at the rear wheels. That represents around 17% driveline loss, which isn’t unusal for a pickup truck. Hennessey previously recorded 20% driveline loss at the rear wheels when it tested a 2019 Ford F-150 Raptor.

The TRX is full-time four-wheel drive, so you might be wondering how Hennessey got dyno results for the rear wheels only. Company founder John Hennessey told Motor Authority that four-wheel drive was disabled by disconnecting the front driveshaft.

While the TRX was designed for off-roading, the amount of power produced by its 6.2-liter supercharged Hellcat V-8 makes this truck pretty quick on pavement. Ram says it will do 0-60 mph in 4.5 seconds.

Inevitably, that wasn’t enough for Hennessey. The company has developed more powerful versions of every Hellcat-powered vehicle, and it’s doing the same with the TRX. Dubbed the Mammoth 1000, Hennessey claims its take on the TRX will boast 1,000 hp, will do 0-60 mph in 3.2 seconds, and run the quarter mile in 11.4 seconds.

To achieve those numbers, Hennessey plans to equip the Mammoth 1000 with an upgraded supercharger, pulley, and air intake, stainless-steel headers, high-flow exhaust piping (retaining the catalytic converter), and new engine mapping. The price for the complete truck is $135,350, and Hennessey only plans to build 200 this year.

Bronze 1965 Shelby 427 S/C Cobra “CSX 4600” is a stunner that’s for sale

Published

1965 Shelby 427 S/C Cobra

The popularity of the Shelby Cobra—combined with the value of original cars—has created a fertile market for replicas. But this Cobra—CSX 4600—is no ordinary replica. It features hand-polished bare metal bronze bodywork, complete with brushed racing stripes. It’s currently up for sale through RM Sotheby’s, with a $475,000 asking price.

The bronze Cobra is the work of Utah-based Kirkham Motorsports. The company has sold Cobra replicas with bodies built at a former aircraft factory in Poland since 1994, a partnership that began when founder David Kirkham has called in to help repair the nose cone of a recently imported fighter jet.

Kirkham bodies are typically aluminum, but the company occasionally tries out other materials. In addition to the bronze CSX 4600, it built at least one car with copper bodywork, according to the listing.

While this car isn’t an original Cobra, it does get a “CSX” serial number, indicating that it is recognized as an authentic Cobra replica by Shelby American. The company has given its blessing—and serial numbers—to a handful of replica builders over the years, and builds its own replicas. That makes modern CSX-numbered cars similar to the “continuation cars” built by automakers like Jaguar, Aston Martin, and Bentley, as they’re officially considered to be a continuation of the original production run.

1965 Shelby 427 S/C Cobra

CSX 4600 is modeled on a 1965 427 S/C Cobra. “S/C” stood for “semi competition,” and denoted a handful of big-block Cobras that were originally built as race cars, but then converted for street use after Shelby failed to get the 427 Cobra homologated for the 1965 racing season.

Under the bronze hood sits a “427 FE” V-8 built by the Carroll Shelby Engine Company, bored and stroked to 511 cubic inches and featuring fuel injection with eight 58-millimeter Borla Induction throttle bodies. The engine makes 650 hp and 670 lb-ft of torque, which is channeled to the rear wheels through a 5-speed manual transmission.

The asking price may be high, but it’s a bargain compared to the millions original Cobras tend to fetch at auction. For example, a 1965 427 Cobra owned by Carroll Shelby sold for $5.94 million at a Mecum Auctions sale earlier this year.

Alternatively, you can have a Cobra replica that departs from the original design. The Superformance MKIII R sports a handful of modern updates, and the company is even planning an electric Cobra.
