Lotus Cortina is the commonly used term for the Ford Cortina Lotus, a high-performance sports saloon, which was produced in the United Kingdom from 1963 to 1970 by Ford in collaboration with Lotus Cars.

The original version, which was based on the Ford Cortina Mark 1, was promoted by Ford as the "Consul Cortina developed by Lotus",[2] with "Consul" later being dropped from the name.

The Mark 2 was based on the Ford Cortina Mark II and was marketed by Ford as the "Cortina Lotus". Lotus gave the model the type number designation Type 28.

There were 3,306 Mark I and 4,093 Mark 2 Lotus Cortinas produced.

Ford Cortina Lotus Mk2

Ford wanted to change a few things for the Mk2, the Mk1 had done all and more than they could expect in competition, but the public linked its competition wins with Lotus and its bad points with Ford. Ford still wanted to build a Mk2 Lotus and compete with it, but Lotus were moving from Cheshunt to Hethel so it was a bad time for them to build another model. Ford were also concerned with the unreliability of the Lotus built cars, so a decision was made at Ford that to continue with its competition drive and make the car more cost effective they would make the car at Dagenham themselves, alongside the other Cortina models. In order to do this the Mk2 had to be much easier to build than the Mk1 so that it could be made alongside Mk2 GT production, just with a different engine and suspension.

The Mk2 took a while to appear, first appearing in 1967. The main difference was the choice of colours and the lack of a stripe, although most had them fitted at Ford dealers at extra cost. The only cosmetic changes made were a black front grille, 5.5J x 13 steel wheels and Lotus badges on rear wings and by the rear number plate. The badge on the front grille was an option at first. Unlike the Mk1, the Mk2 was also made in left hand drive from the start of production.

The Mk2 Cortina Lotus also gained an improved and more powerful (109 bhp (81 kW; 111 PS)) engine, which was formerly supplied as the special equipment engine option on Lotus Elan and the Cortina Lotus Mk1. The gearbox ratios remained 2000E ones but the car now used the Mk2 GT remote-control gearchange. The car also had a different final drive of 3.77:1 rather than 3.9:1. The Mk2 was a wider car than the Mk1, so although they looked the same, the steel wheels had a different offset so as not to upset the tracking, and radial tyres were now standard. Another attraction was the larger fuel tank. The spare wheel could now be mounted in its wheel well, but the battery remained in the boot to aid weight distribution.

The only real difference to the engine bay was the air cleaner mounted on top of the engine. The interior was almost identical to a GT. The Mk2 did exactly what Ford wanted, it was far more reliable whilst still quick enough to be used in competition, until it was replaced by the Escort Twin Cam.

The car did receive a few updates, but none as urgent as the Mk1's. Only a few months after production started, the Lotus badge on the rear panel was cancelled and a new TWIN CAM badge was fitted under the Cortina script on the boot lid.

Despite the badge changes, Ford UK continued to market the model as the "Cortina Lotus".

The new combined clock and centre console was fitted. In late 1968 the entire Mk2 range received some cosmetic changes; for the Lotus, this meant that the 4 dials on top of the dash were brought down and made part of the dash. An internal bonnet release and a more conventional mounting for the handbrake were also phased in. A new single-rail gearshift mechanism was used. The car stayed in production until 1970.

The Cortina Lotus was marketed in Europe as the Cortina Twin Cam in 1969/70.

Two 4-door versions were supplied to the Mid-Anglia Constabulary for evaluation as use as a fast patrol and pursuit car by British Police forces. The trial never went beyond the two vehicles, which are both still in existence.

Racing

To homologate the car for Group 2 Touring Car racing, 1000 were required to be built in 1963, and the car was duly homologated in September 1963. In the same month, in the car's first outing, in the Oulton Park Gold Cup, the car finished 3rd and 4th behind two Ford Galaxies, but beat the 3.8-litre Jaguars which had been dominant in saloon car racing for so long. Soon Ford were running cars in Britain, Europe, and the USA, with Team Lotus running cars in Britain for Ford, and Alan Mann Racing running cars in Europe, also on behalf of Ford. The Cortina Lotus was able to beat almost anything except the 7-litre V8 Ford Galaxies, and later, Ford Mustangs.

In 1964, a Cortina Lotus leading around a bend with its inside front wheel in fresh air became a familiar sight, as the cars were set up with soft rear suspension and a hard front end. Jim Clark won the British Saloon Car Championship easily, in the USA, Jackie Stewart and Mike Beckwith won the Malboro 12-hour, and Alan Mann Racing also performed well in the European Touring Car Challenge, including a 1-2 victory in the 'Motor' Six Hour International Touring Car Race at Brands Hatch. A Boreham-built car also won its class, came 4th outright, and won the handicap section, in the 4000 mile 10-day Tour de France. Other Cortina Lotus achievements included the Austrian Saloon Car Championship, the South African National Saloon Championship, the Swedish Ice Championship, and the Wills Six-Hour in New Zealand.

1965 saw the Cortina Lotus winning regularly, the car being more competitive due to the increased reliability of the new leaf spring rear end. Driving for Alan Mann Racing, Sir John Whitmore dominated and won the European Touring Car Championship in KPU-392C, Jack Sears won his class in the British Saloon Car Championship (a Mustang won outright), Jackie Ickx won the Belgian Saloon Car Championship, and a Cortina Lotus won the New Zealand Gold Star Saloon Car Championship. Other wins were the Nürburgring Six-Hour race, the Swedish National Track Championship, and the Snetterton 500.

In 1966, Team Lotus registered new cars for the British Saloon Car Championship, which was now open to Group 5 Special Touring Cars, as regulations had been changed. Fuel-injection and dry sumping were allowed, and with Lucas injection and tuning by BRM, the engines could produce 180 bhp (130 kW; 180 PS) at 7750 rpm, increasing their ability to stay with the Mustangs. The cars also had the MacPherson struts replaced with coil springs and shock absorbers and a revised wishbone geometry. They scored 8 class wins, many driven by Jim Clark. In the European Touring Car Challenge, Sir John Whitmore scored another four wins, not enough to give him the title, being beaten by Alfa Romeo Giulia GTAs.

Cortina Lotus Mark 1's are a consistent class winner in modern Historic Touring Car racing throughout the world. The fastest official recorded speed is 147 mph (237 km/h) at Mount Panorama Bathurst in Australia by Marc Ducquet. The recorded speed by radar on Conrod Straight was 143 mph.

The car was owned by Bob Pearson and had a 203HP Twin Cam engine built by Randall Edgell in New Zealand. 185/60-13 Radial tyres, 4.3 differential and 9,500 RPM.

Considering the relatively low horsepower of the standard pushrod GT500 Cortina and the Lightweight alloy panelled Cortina Lotus this speed is achievable. For example, the legendary Australian driver "Gelignite Jack" Murray driving a Cortina GT500 - Australia's answer to the Cortina Lotus produced to comply with the local build requirements to be able to be raced of 100 units; initial batch 122, as opposed to running the Cortina Lotus which would have been imported with a minimum requirement of 250 - built by and intended for Harry Firth in the 1965 Bathurst 500 was clocked at 118 mph down conrod straight using a 3.9 diff, Lotus gearbox, large diameter (non radial) tyres and 7,900 rpm.

The Cortina is well known in the USA for its competitiveness in the under 2000 cc class of the Trans Am Series. Canadian born Australian Allan Moffat shocked the outright class cars, winning Round 3 of the inaugural series in 1966 at the Bryar Motorsports Park in Loudon, New Hampshire.

Rallying


Whilst the Cortina Lotus is somewhat overshadowed by the success of the Ford Escort in rallying, it performed admirably in the mid-1960s, which might be surprising, given its reputation for unreliability. The first Cortina Lotus to be rallied was a Cortina GT with the Lotus engine, in the 1963 Spa-Sofia-Liege rally in September, just to try out the engine, and driven by Henry Taylor to 4th place. The first outing in a rally by a Cortina Lotus proper was in the 1963 RAC Rally, campaigned again by Taylor, with co-driver Brian Melia. It finished 6th somehow, in spite of its A-bracket rear end needing constant attention. The A-bracket was persevered with by Vic Elford and David Seigle-Morris for the 1964 Tour de France Automobile, a 10-day, 4,000-mile (6,400 km) event, as it was run completely on sealed roads, unlike the rough RAC Rally. Their car came 4th outright in the Touring Car category, and first in the Handicap category, in a mix of one-hour sprints, hillclimbs, and mountain road rallying.

Still, the general dodginess of the A-bracket suspension meant that Ford decided to replace it with the more conventional GT rear suspension. This became available in June 1965, and while the car still seemed to be afflicted with bad luck, a few victories were racked up. Four of the newly updated cars competed in the Alpine rally of July 1965, and Vic Elford's car led outright, all the way. Well, until less than an hour from finishing, when a piece of the distributor fell out and delayed the car 26 minutes. All four cars retired from that year's RAC rally, which was severely snow-affected. The first works victory came in December 1965, when Roger Clark and Graham Robson won the Welsh International.

In 1966, Ford managed to homologate the car for Group 1, which requires 5000 cars to be built. In the Monte Carlo Rally, Roger Clark finished 4th, only to be disqualified, and then Elford finished 1st in the Rallye Sanremo (Rally of the Flowers), only to be disqualified as well. Elford came 2nd in the Tulip Rally. Bengt Söderström was named victor of the Acropolis Rally, after the 1st-placed Mini Cooper S was disqualified. New cars were used for the Coupe des Alpes (Alpine Rally), where Elford's engine blew up after leading, while Roger Clark finished second. Clark was always competitive, but suffered with unreliable cars, coming 3rd in the Canadian Shell 4000, 2nd in Greece, and 4th in Poland. The Cortina Lotus finally proved itself with an outright win in the RAC rally. F1 World Champion Jim Clark crashed his (twice), but Söderström saw his through to a 13-minute victory, with Gunnar Palm. Other victories in 1966 were in the Geneva rally by Staepelaere, and by Canadian Paul MacLellan in the Shell 4000. A final win before the advent of the Mk. II was also pulled off by Soderstrom in the snowy Swedish Rally of February 1967.
