Jaguar XK140 MC DHC
When Jaguar introduced the XK140 in 1954, it represented a thoughtful evolution of the groundbreaking XK120 rather than a radical departure. The car retained the beautiful flowing lines that had made its predecessor an international sensation, but incorporated meaningful improvements that addressed owner feedback and advancing automotive technology.
The MC designation identified the most potent specification available, featuring the C-Type cylinder head with larger valves and higher-lift camshafts. This modification lifted output to 210 brake horsepower at 5750 rpm, a significant increase over the standard Special Equipment model's 190 bhp. The drophead coupe body style offered the best of both worlds, with a fully lined convertible top that provided proper weather protection while allowing open-air motoring.
Mechanically, the XK140 moved the engine forward three inches and repositioned the battery to the boot, improving weight distribution and creating additional cabin space. The steering gained rack-and-pinion precision, replacing the recirculating ball unit of the XK120. These changes transformed the driving experience, making the car more manageable for daily use while retaining the sporting character that defined the XK series.
The interior received meaningful upgrades including improved seating, more legroom, and better ventilation. The drophead coupe could accommodate two occasional rear passengers, making it the most practical of the three body styles offered. Walnut veneer dashboard trim and Connolly leather upholstery provided an appropriately luxurious environment.
Performance remained exceptional for the era. The MC specification could reach 125 mph and accelerate to 60 mph in approximately 8.4 seconds, making it one of the fastest production cars available. With the optional overdrive gearbox, the XK140 MC was equally comfortable cruising continental highways at sustained high speeds.
Of the 8,884 XK140s produced across all body styles, the drophead coupe accounted for 2,797 units, with a smaller proportion carrying the MC specification. Today, the XK140 MC DHC is highly prized by collectors who appreciate its combination of beauty, performance, and relative rarity. The model occupies a sweet spot in the XK lineage, offering improved refinement over the XK120 with arguably more graceful proportions than the later XK150.
British motoring journalist John Bolster described the XK140 MC as possessing a perfect balance of power and poise, capable of both spirited driving and refined touring in equal measure. It remains one of Jaguar's finest achievements from the golden age of British sports car manufacturing.
Check for chassis corrosion particularly around the front bulkhead and sills. The C-Type head is the most desirable specification; verify its authenticity through the casting numbers. Overdrive units are preferable but can be retrofitted. Brightwork quality varies widely on restored examples. Ensure the wood trim is genuine walnut and not reproduction. Mechanical components are well-supported by specialists like XK Engineering and SNG Barratt.
Produced at Jaguar's Browns Lane factory in Coventry. The MC specification was available across all three body styles but was most popular on the drophead coupe. Left-hand drive models outsold right-hand drive by a considerable margin due to strong American demand.
