Jaguar Classic's 3.8-liter engine block costs nearly as much as a new Jetta

Jaguar is helping collectors restore its vintage models by resuming production of the 3.8-liter six-cylinder engine block it built between 1958 and 1968. Called XK, the straight-six originally powered half a dozen models (including the famous E-Type), and its modern recreation costs nearly as much as a new compact sedan. Wearing part number C22250, the cast-iron block is built to the original's specifications by Jaguar's Classic division, and it comes with a 12-month warranty. Sourcing a used block would likely be markedly cheaper than ordering a new one from the factory, but enthusiasts who value originality above all will appreciate the fact that it comes certificate of authenticity. Customers who send the company proof of vehicle ownership can even retain the serial number from the engine they're pulling out, though an asterisk will identify it as a replacement. Jaguar built the XK engine for several decades, but the 3.8-liter variant only remained in production for 10 years. It powered cars like the surprisingly quick XK 150 roadster, the stately Mark IX and early examples of the E-Type, though its displacement grew to 4.2 liters in 1964. As of this writing, only the 3.8-liter XK is available new. If the E-Type you're painstakingly restoring deserves nothing less than the best, or if you think a 3.8-liter block makes an awesome coffee table, you'll need to send Jaguar a check for GBP14,340 including taxes, a sum that represents approximately $17,800 at the current conversion rate. Enthusiasts will also need to source pistons, connecting rods, a crankshaft and a complete cylinder head, among many other parts, so the cost of a full rebuild will lie well beyond the $20,000 threshold. For context, Volkswagen charges $18,895 for an entry-level Jetta. Related Video:

2013 Jaguar XF 3.0 Supercharged

Generally speaking, I don't get too upset about the growing need to replace displacement in modern cars. Sure, there are exceptions (don't you touch my 6.2-liter AMG V8), but honestly, the industry's new forced induction powertrains are all lovely, and their gains in fuel economy - when they actually make good on them - can make up for the ever-so-slight losses in performance or driving character.
But I'm having a hard time keeping my chin up with this Jaguar XF. For the 2013 model year, Jaguar has killed off the naturally aspirated 5.0-liter V8 and fitted a supercharged 3.0-liter V6 with an eight-speed automatic in its place (and even offers a turbocharged four-cylinder engine below that). That all sounds perfectly well and good, but a week behind the wheel of this British Racing Green sedan just left me missing that V8. And then some.

2017 Jaguar Model Year Preview and Updates

Jaguar, the upscale Brit, is currently enjoying a resurgence in the US, built on an improved value proposition, credible quality, better reliability, and an expanded lineup. That larger lineup now includes an all-new XE four door sedan and Jaguar's first crossover, the F-Pace - pictured above. JAGUAR F-TYPE: An entry-level F-Type has been added to the lineup, improving its accessibility by some $3,600 on the F-Type coupe and roughly $2,700 for the F-Type convertible. XE: Jaguar's compact four door is all-new, and intended to make headway into the sport sedan market long dominated by BMW's 3 Series and, more recently, Audi's A4. The XE brings a tightly drawn platform, responsive drive character and three powertrains to the table, including a 2.0-liter turbocharged diesel. It is on sale now. XF: Jaguar's midsize 'saloon' adds a 2.0-liter turbodiesel to its menu, along with Configurable Dynamics. This optional package allows individual settings for suspension, steering, throttle and transmission. XJ: Jaguar's 2017 XJ builds on the 2016 refresh with the addition of new colors and wheels. F-Pace: Jaguar's first crossover has everything it needs to compete with Porsche's Macan, BMW's X3/X5 and M-B's GLC/GLE. As this suggests, the F-Pace is a 'tweener, sitting between compact and midsize crossovers. It seats five, and is available with either a 2.0-liter turbodiesel or supercharged V6. The line starts at your local Jaguar showroom.
