Lotus Seven

The Lotus Seven is a sports car produced by the British manufacturer Lotus Cars (initially called Lotus Engineering) between 1957 and 1973. The Seven is an open-wheel car with two seats and an open top. It was designed by Lotus founder Colin Chapman and has been considered the embodiment of the Lotus philosophy of performance through low weight and simplicity. The original model was highly successful with more than 2,500 cars sold, due to its attraction as a road legal car that could be used for clubman racing. After Lotus ended production of the Seven in 1973, Caterham bought the rights and today Caterham makes both kits and fully assembled cars based on the original design known as the Caterham 7. The Lotus Seven design has spawned a host of imitations on the kit car market, generally called Sevens or Sevenesque roadsters.

History

=== Series 1 === The Lotus Seven was launched in 1957 to replace the Mark VI as the entry-level Lotus model. The Seven name was left over from a model that Lotus abandoned, which would have been a Riley-engine single-seater that Lotus intended to enter into the Formula Two in 1952 or 1953. However, the car was completed on Chapman's chassis as a sports car by its backers and christened the Clairmonte Special. Externally similar to Chapman's earlier Lotus Mark VI, but with a different tubular frame similar to the Lotus Eleven, the Seven was powered by a 36 bhp (27 kW; 36 PS) Ford Sidevalve 1,172 cc straight-four engine. In addition to the Ford unit, both BMC series A and Coventry Climax FWA engines were available for fitment. Under the Purchase Tax system of the time cars supplied as a kit did not attract the tax surcharge that would apply if sold in assembled form. Tax rules specified assembly instructions could not be included. This situation remained until 1973 and a large proportion of Sevens sold in the United Kingdom were delivered in kit form as a result. The Seven Series 1 was used both on the road and for club racing (750 motor club in the UK). Series 2. The Lotus Seven S2 followed in June 1960 and was supplemented by the Lotus Super Seven S2 from 1961. These were slightly more road-oriented than the Series 1, and received a somewhat simpler chassis. The Series 1's aluminium nosecone was changed to a fibreglass unit. Cycle fenders were originally standard, with clamshell units standard fitment on the 1500, Super Seven, and America or available as an option. While the 1172 cc Sidevalve unit remained available until 1962, the series 2 typically used Ford Kent engines of 1,340 or 1,499 cc from the Ford Consul Classic. These were also available with Cosworth modifi

Performance

=== Road test === A car with a tuned Ford 1172 cc engine and close-ratio gearbox was tested by the British magazine The Motor in 1958. It was found to have a top speed of 80.4 mph (129.4 km/h), could accelerate from 0-60 mph (97 km/h) in 6.2 seconds and had a fuel consumption of 31.0 miles per imperial gallon (9.1 L/100 km; 25.8 mpg‑US). The test car cost £1,157 including taxes of £386. They commented that that car could be bought in component form and then it would have cost £399 for the parts from Lotus, £100 for the Ford engine and gearbox and £27 for the BMC rear axle. Top speed. A Seven's top speed greatly depends upon the body configuration, engine power and gearing. Early models with low-powered engines had difficulty exceeding 90 mph (140 km/h), although a race-prepared Seven was clocked at 127 mph (204 km/h) whilst driven by Brausch Niemann through a speed-trap at the 1962 Natal Grand Prix. In addition, clamshell style wings tend to create drag and generate lift at higher speeds. Cycle wings help alleviate this tendency, and low height Brookland aeroscreens or the lighter Perspex variants that can replace the windscreen help improve top end speed. Sevens do suffer from front end lift at high speed – the nose creates more lift than downforce at speeds over around 70 mph (110 km/h), although retro fitted "winglets" may counter this. Low speed acceleration. Nearly all Sevens, due to their extremely light weight (around 10cwt / 500 kg) have excellent acceleration, especially up to 70 mph (110 km/h), depending on power. The original late 1950s Sevens could beat most contemporary saloon cars—and by the early 1960s, with improved Ford-Cosworth engines could take on most high-performance sports cars with 0–60 mph time in the low 7 seconds.

Mechanical details

=== Engines === Originally equipped with the Ford Sidevalve engine, the Series 2 received the new Ford Kent engine. The original "Super Seven" received versions of the Kent unit with Cosworth modifications. Later, the Kent engine was updated to the crossflow design; this 1.6-litre engine was the most commonly installed one in the Series 3 as well as Series 4. A limited number of earlier cars received Coventry Climax FWA engines, while the later cars were offered with the Lotus-Ford Twin Cam engine. Frame and body. The Lotus Seven was designed with racing in mind, and lightness was of primary concern to Chapman. Like racing cars of the time, it was therefore built around a multi-tube space frame with high sides to allow a stiffer frame (longer lever arm). The Series II and later road versions had simpler frames than the more race-oriented Series I. A front-mounted engine driving the rear wheels (a similar layout to most cars of the day) and a very lightweight steel spaceframe was covered with stressed aluminium panel bodywork. The body panels were mainly flat to avoid the expense of more elaborate curved bodywork, and the simple cloth lined plastic doors were hinged from the windscreen. The nose-cone and wheel arches were originally aluminium parts, but these were replaced in the later S2 and S3 models with painted or self-coloured fibreglass. Weight. Early Lotus Sevens weighed around 1,100 lb (10cwt/500 kg). Although the weight crept upward as production progressed, it remained remarkably low for a production car of over a litre displacement. Suspension. The front was by "A" arms and coil springs with an anti-roll bar serving as the front half of the top A-arm. The rear had trailing arms, a triangular centre locating member, and a solid rear axle.

In popular culture

An S2 Lotus Seven (registration plate "KAR 120C"), driven by creator/director and actor Patrick McGoohan, was featured in the opening titles of the 1967–1968 television series The Prisoner—although the car in the final episode, "Fall Out", was another, driven by Caterham Car's MD Graham Nearn. Marvel Comics superhero Wolverine drives a Lotus Seven. A Lotus Seven appears as one of the stealable cars in Grand Theft Auto: London 1969, under the name "Locust". There is a replica of the Lotus Seven made under the same name and another version made under the trade name of the Locost. In the Sonic the Hedgehog series of video games, the Lotus Seven is said to be the favorite car of Tails. Tails' vehicles in Sonic Drift, Sonic Drift 2, Sonic & All-Stars Racing Transformed, Team Sonic Racing and Sonic Racing: CrossWorlds are based on the Lotus Seven. Tails also appears with an actual Lotus Seven in a hidden screen accessed using the sound test in Sonic CD. In the game Rage Racer the Age Pegase (top-notch handling) is a reference to the Lotus S7. A Super Seven is driven by the character Sena Wakabayashi in the anime series You're Under Arrest. Sōichi Sugano from the anime éX-Driver drives a Super Seven. This series contains several Lotus models, but the Seven is most prominent. Jim Skylark from the anime Gate Keepers drives a Super Seven with license plate AEGIS 02. In the series he debuted in the car, outrunning Shun Ukiya's Toyota Sports 800 (license plate: AEGIS 01) on the freeway. One is featured on the cover of Chris Rea's 1991 album, Auberge. It also appears in the video for the song "Auberge". The car was owned by the guitarist at the time.

Replicas

Because of the Seven's relatively simple design, over 160 companies have offered replicas or Seven-type cars over the years. Many have been challenged over the years by the UK rights-holder, Caterham. Such cars are often referred to as "sevenesque" or simply a "seven" or "se7en". Sometimes they are also called clubmans or "locost". Some examples are: 527 ShortCut from Russia with Lada engine & parts.
