Kia’s new supermini – the eventual replacement for the Rio – will make its first appearance in four-door sedan form at the North American International Motor Show in Detroit in January.

Kia Motors has released the first official sketches and details of the company’s redesigned B-sector challenger.

The all-new Rio-replacement will feature a longer wheelbase, a wider track and more horsepower than its predecessor, providing better handling, a smoother ride and improved levels of performance.

The new car is also roomier than its predecessor, offering more front and back leg room and more overall comfort. The successor’s design is based upon the Kia Sport concept car shown at the Paris Motor Show in September.

Paul Williams, Managing Director of Kia UK said: “The car shown at Detroit will just be a four-door sedan, but we shall be focusing on the five-door hatch as British consumers prefer the extra flexibility.”

The four-door will be available in the North American market with a four cylinder 1.6-litre petrol engine that boasts additional torque and horsepower compared to its predecessor.

In Europe, three engines will be available – a 1.4-litre and 1.6-litre petrol engine and a 1.5-litre diesel engine. All other regions will have a 1.6-litre and 1.4-litre petrol option.
