The original model was highly suessful with more than 2,500 cars sold, due to its attrtion as a road legal car that could be used for clubman ring.After Lotus ended production of the Seven, Caterham bought the rights to it, and today make both kits and fully assembled cars based on the original design. The Lotus Seven design has spawned a host of imitations on the kit car market, generally called Sevens or sevenesque roadsters. Many of those cars are still produced to this day. Along with manufturer supplied kits, there are entirely self-built sevenesque cars referred to as Locosts.The Lotus Seven was launched in 1957, after the Lotus Eleven was in limited production. The Seven na was left over from a model that was abandoned by Lotus, which would have been a Riley-engined single-seater that Lotus intended to enter into the Formula Two in 1952 or 1953. However, the car was pleted around Chapmans chassis as a sports car by its bkers and christened the Clairmonte Special. Based on Chapmans first series-produced Lotus Mark VI, the Seven was powered by a 40 bhp (30 kW; 41 PS) Ford Side-valve 1 nike shox nz scontate ,172 inline-four engine. It was mainly for lower budget club ring on ort trks (750 motor club). The Lotus Seven Series 2 (S2) followed in 1960, and the Series 3 (S3) in 1968. In 1970, Lotus radically changed the ape of the car to create the slight more conventional sized Series 4 (S4), with a squarer fibreglass ell repling most of the aluminium bodywork. It also offered so luxuries as standard, such as an internal heater matrix. The S4 model was not widely weled, and Lotus sold few cars. What is believed to be the oldest of these Series 4′s survives to this day, and can be seen most weekends around Sussex and Kent. A familiar fe at Lotus events up and down the country, this was the second Series 4 ever built, and has proved critics of the S4 wrong; its looks ageing better than many predicted, and its performance and reliability unsurpassed by any of the original Sevens. The Briti tax system of the ti (Purchase Tax) ant the car could be supplied as a kit (known as pletely knocked down or CKD) without attrting the tax surcharge that would apply if sold in assembled form. Tax rules specified assembly instructions could not be included, but in a typical Chapman-inspired piece of lateral thinking, there was no rule covering the inclusion of disassembly instructions. Hence all the enthusiast had to do was to follow these in reverse. Having joined the EEC on 1 January 1973 nike air zoom pegasus 31 donna , the UK had to aboli Purchase Tax and adopt VAT instead. VAT does not allow for concessions such as CKD, so the tax advantage of the kit-built Lotus Seven ca to an end. (Note that VAT does allow for variable rating and even zero-rating of certain goods and services; but the Governnt still opted not to indulge the kit-builder).In 1973, Lotus decided to ed fully its Briti tax system-inspired kit car image and concentrate on limited series motor ring cars. As part of this plan, it sold the rights to the Seven to its only remaining agents Caterham Cars. After a brief period producing the Series 4, including assembly of the last kits supplied by Lotus, Caterham introduced their version of the Series 3, and have been manufturing and refining this car ever since as the Caterham Seven. Replicas 1970 Lotus Super 7 Because of the Sevens relatively simple design, over 160 panies have offered replicas or Seven-type cars over the years. Such cars are often referred to as sevenesque or simply a seven or se7en. Sotis they are also called clubmans. So examples are: A car with a tuned Ford 1172 engine and close ratio gearbox was tested by the Briti magazine The Motor in 1958. It was found to have a top speed of 80.4 mph (129.4 kmh), could aelerate from 0-60 mph (97 kmh) in 16.2 seconds and had a fuel consumption of 31.0 miles per imperial gallon (9.11 L100 km; 25.8 mpg-US). The test car cost ?1157 including taxes of ?386. They nted that car could be bought in ponent 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 Sevens top speed greatly depends upon the body configuration, engine power and gearing. Early models with low-powered engines had difficulty exceeding 90 mph (140 kmh), although a re-prepared Seven was clocked at 127 mph (204 kmh) by Brausch Niemann through a speed-trap at the 1962 Natal Grand Prix.[7] In addition nike air huarache uomo , clamell style wings tend to create drag and generate lift at higher speeds. Cycle guards help alleviate this tendency, and low height Brookland aeroscreens that reple the windscreen help improve top end speed. Low speed aeleration Nearly all Sevens, due to their extrely light weight (around 10cwt 500 kg) have excellent aeleration, especially up to 70 mph (110 kmh), depending on power. For their ti, 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 ti in the low 7 seconds. Braking The choice of brakes vary considerably beeen models and over the evolution of the car. The less powerful early models had drum brakes all round, while more powerful and later models had drums at the rear only (especially on live axle cars from the early 1960s) or discs all round. With the popularity of semi-independent (DeDion) or fully independent Rear suspension most manufturers have opted for discs all round, as is current mon prtice in the automotive induThe pro Photos Source: nike air huarache saldi |
