Jaguar MKIV Sports Saloon 1945 – 1948

Properly named Jaguar 1 ½, 2 ½ and 3 ½ litre the car became known as the Jaguar MK IV, first produced in 1946. To get the company going after five years of war production, Lyons used SS Cars tooling to produce the first model which was originally designed and built as the 1935 SS. Therefore the first cars Jaguar produced were simply re-badged SSs. Only small revisions on the rear axle, brakes, heating and interior were made.

The 1 ½ litre used a Standard Motors engine 4-cylinder OHV, the other two used Jaguar in-house engines designed by Standard but with Jaguar own designed head. The 2 ½ and 3 ½ were pushrod 6-cylinder. Due to the unavailability of high-octane fuel the Jaguar MKIVs were not as lively as they might have been, but what they lacked in raw power they made up for in style.

All Jaguar MKIVs were built on separate chassis frames with semi-elliptic leaf spring suspension, both front and rear. The 1 ½ litre version was 6 inches shorter than it’s bigger brothers. Also as an interesting detail; the cars were marked as ½ litres even though they were not actually 1.5l or so forth. This was only an engine stamp declaring versions of the engines not it’s actual cubic capacity.

Beautiful to behold and very well built, the cars were a testimony to British Engineering in general and Bill Lyons in particular. They were available as `fixed-head saloon` or `drop-head coupe` and were among the most handsome cars of the period. All three models were designed by Lyons himself. Today the Jaguar MKIV is a very collectable car.

About Bev Roberts

Speed, the smell of hot oil, the roar of a straight-through exhaust and the scream of an engine at max revolutions. They have all been a large part of my life for almost 50 years. It is time to share my experiences with you, dear reader. Do you want to know more? Read on through my `Full Bio` and many articles.

View All Posts

I was born in Hereford UK in 1948 and brought up in Gloucester UK. I played Rugby football internationally as a schoolboy. At the age of 17, a new and wet driving license in my paw, I entered motor racing. I was supported and financed by my parents and so my journey began.

In 1965 I bought a 1293cc Mini-Cooper `S` and campaigned it for a season. Having quickly made some good friends in the racing fraternity, several interesting opportunities came my way. I joined a sports-car team and raced in the Le Mans 24 hours in 1968 and 1969 in a Lola T70. Mechanical failure defeated both efforts. During that period I owned and raced a `D type` Jaguar and an AC Cobra. In those days cars like that were available and not too expensive, now they reside in museums and private collections. I had a chain of interesting cars through my youth including Jaguars, Minis, Mustangs and Lotus-Cortinas.

As a young driver I had my share of accidents too. Often the car would only be worth scrap-metal value by the time I got it home! I worked for an Aston-Martin/Jaguar dealership for a while, which enhanced my experience and gave me the opportunity to sample some very exotic machines, Ferrari, Facel-Vega, Iso and Maserati to recall a few of them.

At the end of 1969 I moved to South Africa to work on my uncle`s farm but the S.A. government had other ideas and drafted me into the army. After five years had passed I was thanked and released from the service. While I was there I bought a beige Cadillac Eldorado, previously the property of Marilyn Monroe. While I was away on a patrol my girlfriend had it re-sprayed pink! I was unimpressed by both the joke and the bill for the work!

When I returned to UK in 1974 I left it behind. On my return I found that the once-mighty British motor industry was in decline and was headed for oblivion. Motor racing was now very expensive so I turned to commercial transport. Driving large trucks gave me freedom and a chance to see some of the world. I don`t remember ever making a career choice but for the next thirty years a truck was my home. For about ten years in that period I owned two trucks of my own.

I also owned a famous MGB-GT, known as `Lucky`. If you`d like to read `The Story of Lucky` there is an article in Inopian`s archive. I finally retired, due to ill-health, in 2008. Since I had varied knowledge and many experiences on our subject I decided to share the stories of the cars I enjoyed (and hated) with the new generation.

Enjoy Inopian… it is constructed and written for you.
