LOTUS

UK

In October 1957, Antony Bruce Colin Chapman launched the Lotus 7 at the Earls Court Motor Show.

This Lotus 7 SI was a real track car. It had a space frame chassis, covered with simple aluminium plating, aluminium nose cone and wings. The engine was a 948cc BMC A engine or a Ford 1172cc. It was sold as CKD (complete knocked down) kit to avoid the 25 to 40% British purchase taxes. Everything was included and it took around 12 hours to assemble (approx. 240 sold)

In 1960, it evolutes into Lotus 7 SII. The car now has a simplified chassis to make it cheaper. Nose cone and wings became in polyester. The engines were mostly Ford engines (cheaper than the Coventry Climax engines) from 1000 to 1600cc.

In 1966, Colin Chapman wanted to stop the Seven production. Graham Nearn, from Caterham Cars (Seven specialist), convinced Colin Chapman not to discontinue the Seven and became sole distributor.

In 1967 the Lotus 7 SII registered KAR120C was Patrick McGoohan’s car in the cult series The Prisoner.

The Lotus 7 SIII was the next step in 1968. The rear wings became wider and flatter, and it was powered by Ford 1300 or 1600cc engines or by a Lotus Twin Cam 1600. The production stopped in 1971.

In 1970, the all polyester square bodied Lotus 7 SIV was launched. It had partly a steel sheet front and a tubular rear frame. It was more comfortable than all previous versions. Even a hardtop was available. It was meant for a younger public (Dune Buggy period)

In 1973 Colin Chapman stopped production and sold the rights to Caterham Cars.

CATERHAM

UK

The "ORIGINAL" made in Aluminium

In 1959 they were a Lotus Centre. They specialised in the Seven and formed Caterham Cars.

In 1966 they convinced Colin Chapman not to discontinue the Seven and they became the sole distributor.

In 1973 they bought the rights of the Seven + the jigs & tools for the Lotus SIV + a lot of unfinished cars.

These were sold as turnkey cars, but could no more be badged as Lotus – sourcing parts became difficult, and in 1974 the SIV production ended.

In 1974 they decided to build the SIII with updated components.

In 1985 they introduced the de Dion rear suspension.

In 1988: HPC with Ford Cosworth 1700 engine.

1989: Prisoner series

1990: HPC Vauxhall 175HP

1992: JPE (Jonathan Palmer Evolution) 250HP

Since then, the Caterham is in constant evolution… latest models are the CSR range, the 165 range, etc…

"The Independent Brands" -

 

Lotus & Caterham 7 replica's

 

DAX Rush – Black & Carbon

1996

Ford Pinto 2000cc & 5 speed gearbox

140 hp

590 kg

237 hp / tonne

This is an early Dax Rush model featuring the original round headlights. It has a live axle, a leather interior and an AC Cobra style 4-in-1 open exhaust. The engine has a flowed cylinder head, a Kent fast road cam, a race alternator, an oversized aluminium radiator and Accuspark programmable electronic ignition. The suspension is fully adjustable. The standard weight of 605 kg has been reduced with carbon rear wings and led lights. The bottom is closed and to improve airflow and optimize ground effect there is a carbon diffuser. This provides an extremely fast, steady and predictable ride.
This Dax was originally sold as a kit in the UK, and then imported in Belgium in 2014 by the actual owner. The chassis is from 1996. The engine came from a 1987 Ford Sierra donor car. This typical "fast road" seven is used for road trips and occasional track days.


DAX

UK

1991 – Dax Rush - Originally DJ Sportscars International Ltd built an UK version of the German Rush Mohr Seven – Dax had to redesign the chassis & body, due to legal problems with rival UK Seven manufacturers (the Rush chassis was too much look-alike to the Westfield chassis) – quite large space frame chassis, so it can fit larger drivers – body is partly aluminium and GRP - live axle, de Dion or IRS rear suspension – several Ford or V8 engines as well as motorcycle engines – they introduced the camber compensation and anti roll suspension system at the front.

There was a 4x4 version, the Quadra.

In total about 1400 Rush models should have been built.

The company has now been sold to M.A.N. Motorsport who introduced a new chassis powered with a BMW M3 engine and components.

1985 – S8A – full automobile manufacturing status = end of the kits – only turnkey cars – used new lamination and gluing techniques – survived 2 crash tests – fully IRS rear suspension – Ford 2 litres  & turbo engines (S8AT 170HP)

MNR

UK

MNR Vortx RT and MNR Vortx RT Super (from 2003 on)

MNR Sportscars Ltd. is a relatively newer player in the Kit Car market.

MNR limited - Marc Nordon Racing Company - is formed in 2000 by the British Touring Car Championship driver Marc Nordon and his dad Chris Nordon.

MNR didn't want to be the next builder of 'just another' 7 replica. So Marc Nordon developed his own highly advanced space frame chassis made of round tubes. This extremely light and rigid chassis isn’t comparable to any of the old 7-inspired chassis.

In 2003 the MNR Vortx RT was conceived, a Seven replica using Ford Sierra parts. MNR has now 4 versions of his VortX.

MNR builds street legal racecars, the chassis of the exhibited MNR VortX RT  is equipped as standard with inboard shock absorbers on the front. They are connected to the lower wishbones by pushrods and rockers. The newest models have this advanced suspension not only in the front, but it’s also applied on the rear wheels.

The VortX RT Plus has the same advanced suspension as the VortX RT, but the poly buses are replaced by adjustable bearing rod ends. Therefore the tracking, camber, caster and driving height are fully adjustable and as in the F1, the race driver can experiment endlessly with the adjustment of his race car set up.

Finally, the MNR VortX RT Super is made from high-quality CDS tubes. This makes the MNR VortX the ultimate race and road car in its class!

1991

Ford 1800 Turbo Diesel (Ford Sierra)

110 hp (@ 3900 rpm)

600 kg

183 hp / tonne

This Factory Prototype was built by the Westfield factory and engineer Richard Wilsher from Sword Automotive Systems Ltd in 1991. Richard Wilsher believed that a good diesel engine would be great in a light car. He first installed a diesel engine in the old Westfield SE of a friend of him. He was along the way with the project for a month or 2, cutting, modifying, welding, adapting, etc. Chris Smith (Westfield) heard about it. He found it an interesting project and offered Richard a brand new Westfield Seight chassis. The Sierra engine has been highly modified: a large intercooler (Sierra Cosworth), a Garret T3 turbo instead of the T2 version, an improved exhaust, a modified Lucas CAV fuel pump, modified combustion chambers and flowed head, increased boost from 12 to 20 psi, etc. The engine was mated to a 5 speed gearbox from a Ford P100 pick up. The power has raised from 75 to about 110 – 120 hp. The car has been raced some times by Chris Smith. Testing the car at Millbrook, in February 1992, Autocar Magazine achieved some remarkable performance figures: 0 to 100 km/h in 6,6 seconds, 0 to 145km/h in 15,2 seconds, 400 m standing start in 15,2 seconds and a top speed of 173 km/h.

During the test, the consumption was around 4,05 l/100km.

The factory being very busy with the introduction of the ZEi production and Richard Wilsher being busy with projects keeping his business running, no time was available for further development. The car remained in a corner of the Westfield factory till it was sold to Mr Barnes in 1993. He kept it till 2000. He became the owner, but the installed engine remained property of Sword Engineering. Some further developments were done now and then. Till now, the Weasel has only done 15.000 miles.
