Rare Rides: The Sports-Luxury 1966 Jaguar S-Type 3.8

Long before the Ford-based retro throwback began showing up on dealer lots, Jaguar produced a contemporary and modern sedan called the S-type. Let’s check out a brown example, this one hailing from 1966.



The roots of the original S-Type lie within its predecessor, the Mark 2 (Mk. II). As with many British automakers, under the skin of a new model lay a reworked version of an older vehicle.

Much like the 2000s S-Type, the original was intended as a more affordable luxury alternative to Jaguar’s flagship sedan offering. At the time, the S-Type was the alternative to the large Mark X. Jaguar founder Sir William Lyons realized, after looking at the company’s new and technologically advanced Mark X and E-Type models, that the Mark 2 was in need of a revision. Engineers set to work.

The well-known styling of the Mark 2 saw some rework, resulting in a more modern look. Jaguar elongated the rear of the sweeping sedan for a smoother appearance, with the interior trim seeing its own update. Critically, the live rear axle suspension was replaced with an independent setup. The longer flanks and additional luxury equipment meant a weight gain of 335 pounds over the Mark 2, but Jaguar’s engineers (or accountants) did not feel that any changes to the braking system were necessary. The panned steering of the Mark 2 was replaced with a tighter power steering system promising more driving feel.

S-Types engines were hand-me-downs from other Jaguar vehicles. The S-Type was first introduced with the 3.8-liter engine from the Mark 2, with a lower-end 3.4-liter engine available a bit later. Jaguar was careful with its engine presentation. No 3.4-liter models were sold in the United States, and said engine was omitted from press demonstration cars in the United Kingdom. The 3.8 was the more popular engine choice by a 3 to 2 ratio in the S-Type, even though the 3.4-liter was more popular in the Mark 2. Even though both engines could be had with triple carburetors by that time, the S-Type’s engines only had two. The triple setup would not fit into the dated Mark 2 engine bay of the S-Type. Transmission options included a four-speed manual, four-speed with overdrive, or a three-speed automatic.

Mark 2 revisions complete, the S-Type hit dealer lots in 1963. The brand’s product lineup at the time included the E-Type coupe, as well as the Mark X, Mark 2, and 420 sedans, in addition to the new S-Type. While the Mark X did not grab buyers as well as hoped, the Mark 2 ended up selling better than expected, even at its advanced age. Lyons decided to maximize sales possibilities and sell all four at the same time. Things stayed this way through 1967, with the Mark X renamed as 420G.

The new XJ6 came along in 1968, replacing all of Jaguar’s sedan offerings (with the exception of the 420G).

Today’s Rare Ride is located in central Illinois, and, with 78,000 miles on the clock and excellent patterned fabric seats, asks $6,000.

Interested in lots of cars and their various historical contexts. Started writing articles for TTAC in late 2016, when my first posts were QOTDs. From there I started a few new series like Rare Rides, Buy/Drive/Burn, Abandoned History, and most recently Rare Rides Icons. Operating from a home base in Cincinnati, Ohio, a relative auto journalist dead zone. Many of my articles are prompted by something I'll see on social media that sparks my interest and causes me to research. Finding articles and information from the early days of the internet and beyond that covers the little details lost to time: trim packages, color and wheel choices, interior fabrics. Beyond those, I'm fascinated by automotive industry experiments, both failures and successes. Lately I've taken an interest in AI, and generating "what if" type images for car models long dead. Reincarnating a modern Toyota Paseo, Lincoln Mark IX, or Isuzu Trooper through a text prompt is fun. Fun to post them on Twitter too, and watch people overreact. To that end, the social media I use most is Twitter, @CoreyLewis86. I also contribute pieces for Forbes Wheels and Forbes Home.

  • Redapple2 Love the wheels
  • Redapple2 Good luck to them. They used to make great cars. 510. 240Z, Sentra SE-R. Maxima. Frontier.
  • Joe65688619 Under Ghosn they went through the same short-term bottom-line thinking that GM did in the 80s/90s, and they have not recovered say, to their heyday in the 50s and 60s in terms of market share and innovation. Poor design decisions (a CVT in their front-wheel drive "4-Door Sports Car", model overlap in a poorly performing segment (they never needed the Altima AND the Maxima...what they needed was one vehicle with different drivetrain, including hybrid, to compete with the Accord/Camry, and decontenting their vehicles: My 2012 QX56 (I know, not a Nissan, but the same holds for the Armada) had power rear windows in the cargo area that could vent, a glass hatch on the back door that could be opened separate from the whole liftgate (in such a tall vehicle, kinda essential if you have it in a garage and want to load the trunk without having to open the garage door to make room for the lift gate), a nice driver's side folding armrest, and a few other quality-of-life details absent from my 2018 QX80. In a competitive market this attention to detai is can be the differentiator that sell cars. Now they are caught in the middle of the market, competing more with Hyundai and Kia and selling discounted vehicles near the same price points, but losing money on them. They invested also invested a lot in niche platforms. The Leaf was one of the first full EVs, but never really evolved. They misjudged the market - luxury EVs are selling, small budget models not so much. Variable compression engines offering little in terms of real-world power or tech, let a lot of complexity that is leading to higher failure rates. Aside from the Z and GT-R (low volume models), not much forced induction (whether your a fan or not, look at what Honda did with the CR-V and Acura RDX - same chassis, slap a turbo on it, make it nicer inside, and now you can sell it as a semi-premium brand with higher markup). That said, I do believe they retain the technical and engineering capability to do far better. About time management realized they need to make smarter investments and understand their markets better.
  • Kwik_Shift_Pro4X Off-road fluff on vehicles that should not be off road needs to die.
  • Kwik_Shift_Pro4X Saw this posted on social media; “Just bought a 2023 Tundra with the 14" screen. Let my son borrow it for the afternoon, he connected his phone to listen to his iTunes.The next day my insurance company raised my rates and added my son to my policy. The email said that a private company showed that my son drove the vehicle. He already had his own vehicle that he was insuring.My insurance company demanded he give all his insurance info and some private info for proof. He declined for privacy reasons and my insurance cancelled my policy.These new vehicles with their tech are on condition that we give up our privacy to enter their world. It's not worth it people.”
