Background
The XK120 was first shown to the world at the 1948 London Motor Show.
With a slim waist and alluringly voluptuous curves that would put Jessica Rabbit to shame, it caused weak men to gibber and strong women to faint.
Once seen, the XK120 was forever coveted.
Arriving in late 1954, the XK140 introduced numerous improvements over the XK120 and was again offered in Fixed-head coupé (FHC), Drop-head coupé (DHC) and Open Two-Seat Roadster (OTS) versions, all with a subtly restyled body.
Underpinning the body was a redesigned box-section chassis with a larger torsion bars and anti-roll bars, improved brakes, and rack-and-pinion steering to replace the earlier recirculating-ball system.
Perhaps most importantly for customers in the vital North American market, there was a more comfortable cockpit with increased legroom, thanks to the engine and transmission assembly being moved forward by three inches, along with the firewall and instrument panel. The cowling and steering wheel were both raised. Larger full-width bumpers and new body trim helped differentiate it from the outgoing 120.
Beneath the bonnet and redesigned grille sat the 3.4-litre twin-cam six from the XK120 SE, with higher-lift camshafts and an improved ignition system. A four-speed manual transmission carried over, and electric overdrive was an option.
Although the XK140 was a few hundred pounds heavier than the XK120, it was also faster, with a top speed of about 130 mph in standard form.
