Six Sells: Stellantis Introduces Twin-Turbo Inline-Six for Ram, Jeep

The auto industry might be moving headlong into all-electrics but that doesn’t mean internal combustion is dead, not by a long shot. Witness the introduction of a brand-new engine from Stellantis, a turbocharged inline-six that will be capable of generating more than 500 horsepower.

Development of this ‘Hurricane’ I-6 was kept on the down-low, at least as much as can be expected during these modern times when everyone has a camera in their pocket. Two variants will be available when the engine goes into production and pops up in showrooms later this year.

Junkyard Find: 1987 Jaguar XJ6

Jaguar built the Series III Jaguar XJ for the 1979 through 1992 model years, and so I’ve been seeing these cars in the big self-service vehicle graveyards since, well, the middle 1980s. They still show up in such yards to this day, as long-neglected project cars get swept up in yard- and driveway-clearance projects, but I’ll only document those that are particularly interesting.

A very clean British Racing Green XJ6 from the last model year for the Series III’s straight-six engine certainly qualifies, so here we go!

Going Straight: 2020 Range Rover Swaps V6 for Inline Engine

After becoming the preferred choice for manufacturers delivering both mainstream autos and high-end performance vehicles, the V6 is starting to lose ground to its inline counterpart. Numerous automakers are replacing twin banks with one long one.

Despite the V6’s packaging advantages, mild hybridization and the standardization of modular engines has made the more-affordable straight six increasingly viable. Environmental regulations have also convinced many automakers to downsize, leaving large automobiles with V8-sized engine bays that can more easily accommodate a longer unit with fewer cylinders.

While Mercedes-Benz is probably the automaker best known for helping the I6’s resurgence, it’s not alone. Jaguar Land Rover is also abandoning the V6 for something straighter. Having already shown off its next-gen mill inside the Range Rover Sport HST, the brand now plans to install it in its flagship SUV for the 2020 model year.

Junkyard Find: 1994 Volvo 960 Sedan

While I live in Denver, my family and work ties in the San Francisco Bay Area make me a regular visitor at the incredibly well-stocked self-service wrecking yards of the region between San Jose and Richmond. These yards don’t have quite the selection of Subarus and IHC Scouts that I see in the yards around Denver, but they make up for that shortage by stocking plenty of BMWs, Mercedes-Benzes, and Volvos.

Just last week, I found a half-dozen 240s, a 780 Bertone Coupe, and a pair of 960 sedans… in a single yard. Here’s the better-preserved of the two 960s.

Junkyard Find: 1953 Pontiac Chieftain Sedan

More pre-1960 vehicles than one might think show up in the big U-Wrench wrecking yards; you won’t find a ’55 Chevy coupe, but I’ve seen Nash Metropolitans, a ’55 Buick, a ’49 Dodge, a ’58 Edsel, a ’53 Willys, and a ’50 Studebaker in recent years, and that’s just a small sampling. Today’s Junkyard Treasure is a ’53 Pontiac Chieftain sedan in very solid condition, photographed in a Denver-area self-service yard last week.

Aston Martin May Return to the Inline Six With Help From Mercedes-AMG

While the United States’ obsession with massive V8 engines was picking up steam, Britain was falling in love with the inline six. In the years following World War II, Aston Martin was acquired by David Brown for a pittance and entered into the era that would define it forever. This era included the engine stylings of Tadek Marek — a man with a serious penchant for the straight six. Eventually both Aston and Marek would move on to motors with more cylinders, but the company would still hold onto the inline six until the new millennium as an entry-level option. It’s last application was on the base-model DB7.

Unless you count the DB4’s continuation, we’ve not seen any Aston Martin hosting a straight-six configuration since then. However, the company recently let slip that it’s talking about borrowing one from Daimler. Specifically, the turbocharged 3.0-liter from Mercedes-AMG.

The Straight Six is the Best Six - And It's Making a Comeback

As a parent of two young children, I watch a lot of movies at home. Most of the blockbuster movies I’ve watched this year are remakes. This month alone, I watched Ghostbusters, Star Trek Beyond, and Star Wars: The Force Awakens. All three are part of franchises that died a decade (or more) ago and have been reborn successfully in 2016.

In the same way, inline-six engines have returned to Mercedes-Benz after nearly a 20 year hiatus in North America.

Why are straight six engines making a comeback?

Piston Slap: Of Head Bolts, Bad-Ass Sedans…

Earl writes:

I just bought a mint condition, dealer-maintained 1990 Cressida. I am aware of the head bolt torque issue on the 6 cylinder engine. The car shows no sign of head gasket issues. My question: should I have my dealer simply re-torque the head bolts? Their tech (30-year’s experience) says he’s done this on many cars with no issues. Your thoughts?

  • The Oracle Well, we’re 3-4 years in with the Telluride and right around the time the long term durability issues start to really take hold. This is sad.
  • CoastieLenn No idea why, but nothing about a 4Runner excites me post-2004. To me, they're peak "try-hard", even above the Wrangler and Gladiator.
  • AZFelix A well earned anniversary.Can they also attend to the Mach-E?
  • Jalop1991 The intermediate shaft and right front driveshaft may not be fully engaged due to suspected improper assembly by the supplier. Over time, partial engagement can cause damage to the intermediate shaft splines. Damaged shaft splines may result in unintended vehicle movement while in Park if the parking brake is not engagedGee, my Chrysler van automatically engages the parking brake when we put it in Park. Do you mean to tell me that the idjits at Kia, and the idjit buyers, couldn't figure out wanting this in THEIR MOST EXPENSIVE VEHICLE????
  • Dukeisduke I've been waiting to see if they were going to do something special for the 60th Anniversary. I was four years old when the Mustang was introduced. I can remember that one of our neighbors bought a '65 coupe (they were all titled as '65 models, even the '64-1/2 cars), and it's the first one I can remember seeing. In the '90s I knew an older gentleman that owned a '64-1/2 model coupe with the 260 V8.
