The Renault R31 was a Formula One racing car designed by Lotus Renault GP for the 2011 Formula One season.
 The car's distinctive black and gold livery was designed as a tribute to the Team Lotus cars of the 1980s and the famous John Player Special liveries (those cars also used Renault engines).
 Speculation suggested that as the design is reminiscent of a cigarette package, the team would be in violation of strict anti-tobacco laws in Canada and would be unable to use it at the 2011 Canadian Grand Prix.
 However, senior team personnel dismissed the claims, stating that "another famous team" was racing with colours similar to those of another tobacco brand and had done so in Canada without trouble in previous years.
 Ultimately, the car raced in Canada with no changes to its livery.

 Lotus cars include the Esprit, Elan, Europa, Elise and Exige sports cars and it had motor racing success with Team Lotus in Formula One.
 Lotus Cars are based at the former site of RAF Hethel, a World War II airfield in Norfolk.
 The company designs and builds race and production automobiles of light weight and fine handling characteristics.
 It also owns the engineering consultancy Lotus Engineering, which has facilities in the United Kingdom, United States, China, and Malaysia.
The Lotus 94T was a Formula One racing car used by Team Lotus in the second part of the 1983 Formula One season.
 The car was powered by the Renault Gordini EF1 V6 turbo engine, and ran on Pirelli tyres.
 The car was designed and built in only six weeks by incumbent designer Gérard Ducarouge, who was brought into the team by boss Peter Warr in an attempt to stave off the uncompetitiveness of the previous Lotus cars.
The Lotus 22 was a racing car built by Lotus cars in 1962, and a total of 77 cars were built.
 It was developed from the 1962 Lotus 20, with the major differences that it had disc brakes all round, a top link and the 'rubber donut' to the rear suspension and a dry sump engine that was canted over to lower the centre of gravity.
 Also notable is the smoother bodywork covering the engine, compared to the boxy design of the 20.
The Lotus 39 was a single-seat racing car produced by Team Lotus.
 It was originally intended for use in Formula One, to be powered by the Coventry Climax 1.5 litre flat-16 engine.
 But the engine never eventuated, so the chassis was modified by Maurice Philippe to accept a 2495 cc Coventry Climax FPF engine, which produced about 230 bhp , and was used for the 1966 Tasman Series races in Australia and New Zealand.
 In the hands of Jim Clark, the 39 scored 1 win, 5 second places and 1 third place and Clark finished second in the series behind Jackie Stewart.
The Alfa Romeo P3, P3 monoposto or Tipo B was a classic Grand Prix car designed by Vittorio Jano, one of the Alfa Romeo 8C models.
 The P3 was first genuine single-seat Grand Prix racing car and Alfa Romeo's second monoposto after Tipo A monoposto (1931).
 It was based on the earlier successful Alfa Romeo P2.
 Taking lessons learned from that car, Jano went back to the drawing board to design a car that could last longer race distances.
 The P3 was the first genuine single seater racing car, and was powered by a supercharged eight-cylinder engine.
 The car was very light for the period, weighing just over 1,500 lb (680 kg) despite using a cast iron engine block.
The Lotus 16 was the second single-seat racing car designed by Colin Chapman, and was built by his Lotus Cars manufacturing company for the Team Lotus racing squad.
 The Lotus 16 was constructed to compete in both the Formula One and Formula Two categories, and was the first Lotus car to be constructed for Formula One competition.
 Its design carried over many technological features of the first Lotus single-seater, the Lotus 12, as well as incorporating ideas which Chapman had been developing while working on the Vanwall racing cars.
 Indeed, such was the visual similarity between the Vanwall and Lotus 16 designs that the Lotus was often dubbed the ""mini Vanwall"" by the contemporary motor sport press.
 Although the Lotus 16 only scored five Formula One World Championship points in the three seasons during which it was used, its raw pace pointed the way for its more successful successors, the Lotus 18 and 21.
Anthony Colin Bruce Chapman CBE (19 May 1928 – 16 December 1982) was an influential English design engineer, inventor, and builder in the automotive industry, and founder of Lotus Cars.
The Lotus E20 is a Formula One racing car designed and produced by the Enstone-based Lotus F1 Team for the 2012 Formula One season.
 The E20 was the twentieth Formula One car to be designed at Enstone since 1992, and was named in tribute to the contribution made by the facility and its personnel in their twenty-year history.
 The car was also the first from Enstone to carry the Lotus name, since the team ceased using the Renault name following their renaming from Lotus Renault GP at the end of 2011.
 The team continued to use Renault engines for the car.
 The car, which was launched by the team on its website on 5 February 2012, was driven by 2007 World Drivers' Champion Kimi Räikkönen and 2011 GP2 Series champion Romain Grosjean, both of whom returned to Formula One after a two-year absence.
Team Lotus was the motorsport sister company of English sports car manufacturer Lotus Cars.
 The team ran cars in many motorsport series, including Formula One, Formula Two, Formula Ford, Formula Junior, IndyCar and sports car racing.
 More than ten years after its last race, Team Lotus remained one of the most successful racing teams of all time, winning seven Formula One Constructors' titles, six Drivers' Championships, and the Indianapolis 500 in the United States, between 1962 and 1978.
 Under the direction of founder and chief designer Colin Chapman, Lotus was responsible for many innovative and experimental developments in critical motorsport, in both technical and commercial arenas.
