Based on the chassis of the earlier coupé and the Ogle Design GTS estate car experiment, the four-seater Scimitar GTE SE5 came with either a 2.5L or 3.0L engine. The 3.0L engine, which gave this model a top speed of over 120mph (193km/h), was more popular, and the 2.5L version was later dropped. A Borg-Warner automatic transmission was added as an option in 1970 and by 1971, overdrive on the 4-speed manual was offered. In 1972 several improvements were included in the upgrade to SE5A, including a boost in power. The extra 7hp (5kW) and maximum engine speed raised performance quite a bit and the GTE was now capable of 0-60mph (100km/h) in 9.3seconds and top speed was raised by 6mph (10km/h). The SE5's flat dashboard also gave way to a lower quality curved and moulded plastic one.
Less than 2500 SE5s were produced. The 5A model sold more than any other Scimitar, with approximately 6630 manufactured.
More of a luxury model than the SE5, the SE6 series was promoted to the executive market. These models were two-door sports estates, again with the Ford V6 3.0L engine, and were a few inches longer and wider than their predecessor. The SE6 had some quality issues and was soon replaced by the SE6A. About 550 SE6 models were produced.
The SE6A displayed a number of improvements, including better quality brakes and road-holding. There was also the option of power steering. 3908 SE6As were made.
Ford had stopped making the "Essex" engine by 1979, so one of the major differences with the SE6B was the engine choice. The Ford "Cologne" 2.8L V6 was used instead, and provided similar power but rather less torque. The final drive ratio was changed to compensate.
Only 407 production SE6Bs were manufactured. Production ceased by 1986.
The convertible version of the Scimitar GTE was known as the Scimitar GTC, or SE8B. When the hood (top) was folded down a fixed rollover bar was left in place over the car mounted just behind the doors. It was modelled closely on the SE6B and still included four seats and the 2.8L "Cologne" engine.
