Background
Introduced at the 1948 London Motor Show, lithe looks, a throaty 160bhp six-cylinder heart and a top speed of 120mph ensured that the light alloy bodied XK120 roadster was an instant and roaring success.
In truth though it was a sticker price of just £1298 that most definitely did the deed. The world’s fastest production car was a bit of a blimmin’ high-performance bargain.
Just 240 examples were constructed before production switched to steel but performance remained, to use modern terminology, properly stonking; and to prove so, Jaguar took an XK120 to Jabbeke in Belgium where it clocked a whip-cracking 126mph.
A fixed-head Coupe arrived in 1951, bringing a roof to the party and a more elegant aesthetic. The SE upped the power stakes to 180bhp, before the new XK140 took up the reins in 1957.
You’d have been hard pressed to spot the difference between new model and old; the differences limited to the number of spokes on the front grill, bumper overriders and a badge on the boot-lid celebrating the XK120 C-Type’s Le Mans successes.
The 3.4-litre XK unit now output 190bhp (210bhp in the SE). In came rack and pinion steering as standard and the gearbox now had an optional overdrive (you could even spec an automatic ‘box should you so wish).
The last hurrah for the XK line (if not the engine) came in the form of the 1957 XK150. This thoroughly modern Millie had a one-piece windscreen and less pronounced wing lines to bring it aesthetically up-to-date.
You could still have the XK140’s power outputs via the 3.4-litre unit, but in S form that was now upped to 220bhp. On the road it was a far more capable beast, both in terms of oomph and road holding.
Come 1959 and the 3.8-litre unit was now the only option with 220bhp or in S form, a whopping 265bhp! This firecracker had come a long way from the original XK and a 138mph top speed was now the order of the day.
For those unaware of Jaguar's XK production numbers, and therefore how rare this Jaguar is, only 926 S Roadsters, 249 S FHCs and 140 S Coupes were made. Only a minority had the 3.8-litre engine, and even fewer were in RHD. In fact, Jaguar only built 23 OTS (Roadsters), 69 DHC and 115 FHCs in 3.8-litre S, RHD form, which of course today makes them rare in the extreme. May we introduce you to one….
