Berkeley Cars

Berkeley Cars Ltd was a British car manufacturer based in Biggleswade, Bedfordshire. The company produced economical sporting microcars with motorcycle-derived engines from 322 cc to 692 cc and front wheel drive between 1956 and 1960. About 4,100 cars had been sold before bankruptcy in 1960.

History

The Berkeley automobile was a collaboration between designer Lawrence "Lawrie" Bond and the Berkeley Coachworks factory owned by Charles Panter, which at the time was one of the largest manufacturers of caravans in Europe. It was an ideal project for Berkeley, who had developed considerable skills in the use of Glass-reinforced plastic (GRP), and were looking for something to fill the gaps in the very seasonal caravan market. What Panter and Bond wanted to achieve was "something good enough to win World 750cc races... but cheap, safe, easily repairable and pretty."

The early cars were an immediate success on the home market, and several derivative models were spawned over the four years of car production. Export markets, most notably the United States, were exploited and the cars earned a reputation for fun, if fragile, sports motoring on a budget. Recognising the threat posed by the newly introduced Mini and Austin-Healey Sprite in the late fifties, the company started to develop a more conventional model with the support of Ford Motor Company.

The caravan market collapsed towards the end of 1960, and Berkeley's cash flow problems forced the company into liquidation on 12 December 1960, taking its car manufacturing activities with it. After having produced about 4100 cars of various types, the workforce was laid off shortly before Christmas that year. An attempted sale of the company to Sharp's Commercials Ltd (manufacturer of the Bond Minicar) came to nothing, and the company's assets were liquidated in 1961.

The factory was later used by Kayser Bondor Ltd to make women's underwear, but it was demolished in 2002 and the site turned over to housing. A road named 'Berkeley Close' in the housing estate provides the only obvious link to the car factory.

Today there is an owner's club (the Berkeley Enthusiasts' Club), which provides a range of parts and services aimed at preserving the remaining few hundred cars known to survive worldwide.

Models

Sports (SA322)

Berkeley's first production car was the 'Sports' (type SA322), announced in September 1956 and produced from October 1956 to January 1957. Production began with two prototypes (registered RMJ395 and RMJ946), which were seen being tested around the neighbourhood of Biggleswade in the late summer of 1956. Stirling Moss drove one at Goodwood in September, and the car was launched to the public at the 1956 London Motor Show – one year ahead of the Lotus Elite, which was also to be of fibreglass monocoque construction.

Bond's 2-seater open tourer design capitalised on Berkeley's GRP experience, and consisted of three large mouldings (floor or 'punt', nose, tail) with no conventional chassis. The front edges to the doors slanted forward so that when the doors were opened they hinged upwards and then closed by themselves. Although usually configured as a two-seater with a bench seat, a hatch could be removed from behind the front seat, revealing a compartment normally containing the spare wheel and some luggage space which could double as a basic seat for a small child. John Bolster tries the Berkeley, Autosport Magazine, 21 September 1956 Equipment was basic, the fuel gauge was an optional extra.

Power was provided by a British Anzani twin-cylinder 322 cc two-stroke engine producing and mounted transversely, driving the front wheels via a chain and three-speed gearbox. The engine was already used by various motorcycle manufacturers such as Cotton and Greeves, but in the Berkeley was fitted with a Siba Dynastart to provide both battery charging and electric starting. It was an advanced two-stroke engine which incorporated a rotary inlet valve mechanism in the centre of the crankshaft.Modern Engines - 322cc British Anzani Uni-Twin, The Motor Cycle, 17 May 1956 The gearbox was a three-speed Albion HJR5, using a steering column-mounted gearchange.

The car had all-round independent suspension by coil springs and in spite of the small engine gave remarkably good performance owing to its light weight (kerb weight is ) and excellent roadholding. Girling hydraulic brakes with drums were used.

The identification plate was a plain stamped alloy rectangle fitted on the engine bay side wall just above the Dynastart and marked SA322 B1 etc. (Sports Anzani 322 cc Berkeley Chassis number 1).

Sports (SE328)

After 163 of the SA322 cars had been manufactured, a change was made to the SE328 model with a 328 cc Excelsior engine offering . The production run ran from Jan 1957 to April 1958 with chassis numbers from 164 to 1422, many being exported to the United States where it sold for approximately $1600 (equivalent to $ today). The manufacture touted the number 70, meaning it could reach and had an average fuel economy of 70 mpg. The export model was differentiated by having separate headlamps whereas on the home market they were faired into the wings, although the export type lamps could be specified.

Early cars from Jan 1957 to about chassis number 476 in June 1957 still used a column gear change. During their production run a Deluxe model was offered which was bodily the same but featured polished wheel trims and spinners, tachometer and twin carburettors. The chassis plate was similar to the Anzani type on the early cars but was later changed to a printed type fitted to the bulkhead above the brake master cylinder. The printed type chassis plate had type ‘SE328’ printed on it. Most of these cars were supplied with a three-speed gearbox similar to the Anzani except for the mounting flanges. All of the cars had the sloping leading edges to the doors.

Motor magazine tested a 328 cc Berkeley in 1957 and found it to have a top speed of and acceleration from 0– in 30.6 seconds. Fuel consumption of was recorded. The test car cost £574 on the home market including taxes of £152 (equivalent to £ today).

The SE328 enjoyed considerable success and press exposure through their involvement with lightweight motor racing, and their famous drivers included Pat Moss who drove one in the 1958 Liège-Brescia-Liège rally for cars up to 500 cc. The Berkeley team – a works-supported entry of six cars including BBC commentator Robin Richards – led as far as Slovenia, but slow climbing in summer heat found their weakness and Moss ended up being towed back to Italy by another Berkeley. None of the Berkeleys finished the event.

Sports and Twosome (SE492)

In late 1957 a new derivative model was introduced, using a , Excelsior three-cylinder 492 cc engine with triple carburettors. This engine configuration was made possible by the vertically split crankcase of the Excelsior engine and modular crankshaft and barrels, which made adding a central cylinder relatively easy. A four speed gearbox was standardised. The top speed was now . Production ran from October 1957 to March 1959 with chassis numbered 1 to 666. From about October 1958, in order to coincide with the introduction of the 'Foursome' (see below), they were renamed the ‘Twosome’. Also at the 1958 Motor Show a Fixed Head (or Hardtop) was announced and displayed that had external as well as the usual internal door handles, but there are no records that this body style actually reached production.

It is probable that cars pre chassis number 120 (approx), about April 1958, had similar bodies to the early Berkeley "Sports" cars. Cars from about April 1958 to the end of production had vertical front door edges and internal door hinges, as well as body moulding and a few mechanical changes. Early cars were fitted with the four speed TR gearbox whilst later cars had the larger and stronger VR gearbox.

The cars enjoyed some success in Motor Sport and Giovanni Lurani bought three which he took to Italy, fitted them with his own design of hardtop, and running them in the 750 cc GT class, one driven by Lorenzo Bandini finishing first in the 1958 Monza 12 hour race.

Reliability of the air-cooled two-strokes, became more of an issue with the extra heat generated by the triple, and there were a number of recorded reports of warranty claims.

Foursome

Announced in October 1958, this model was wider and longer than its forebears and differed structurally in that the rear swinging arms were lower and external to the body, and the spare wheel was mounted at the rear of the car. The type reference is supposed to be SE492/4 but one has the reference B.100. The chassis numbers are D1/1 to D1/19 but then again one example has D1/100, this particular car could be the prototype since it appears in publicity pictures.

The list price of the Foursome was £700 including Purchase Tax, with an additional £28 for the optional hardtop (equivalent to £ and £ today).

B95 and B105

The B95 and B105 models were launched at the 1959 Geneva Motor Show and boasted more power from twin-cylinder Royal Enfield
