Honda’s Swindon plant builds the Civic hatchback (which has a starting price of £18,895) and Civic Type R hot hatch for global markets, but the Civic saloons will come from Honda’s production facility in Turkey.
Two engines will be offered in the saloon: a 127bhp 1.0-litre petrol and 118bhp 1.6-litre diesel. The former will be available with a six-speed manual or CVT automatic gearbox, while the diesel will offer a choice of the same manual or a nine-speed automatic.
Honda is yet to reveal whether the engine line-up will grow in future (the hatchback has two more petrol options), or whether it could receive the hybrid powertrain that's set to arrive in the brand's new CR-V SUV. The previous Civic saloon was sold in Britain exclusively with hybrid power.
The new car is longer (at 4644mm) and slightly taller (at 1416mm) than the hatchback, but its width (1799mm) and wheelbase are unchanged.
Much of the Civic saloon's appeal will come with its greater interior space. Leg room for the saloon is 1074mm in the front and 950mm in the rear. It can swallow 519 litres of luggage, 99 litres more than the hatchback.
Trim levels for the saloon will mirror the hatchback; the starting price is applied to cars of SE spec, with SR and EX sitting above this. All variants come with a suite of driver assistance technology, including automatic emergency braking, lane-keeping assistance and adaptive cruise control. CVT and automatic models get low-speed following capability, too.
SR models add more kit, including automatic wipers and lights, dual-zone climate control and parking sensors. EX cars get more extras, such as LED lights, leather seats and wireless smartphone charging.
A Honda spokesman said that the new four-door variant "completes the line-up for the Civic family in the UK". He continued: “With the hatchback and four-door now available, we have a strong Civic range, whether it’s a corporate or retail customer looking for a car.”
