Kia has added a new top-of-the-range '4' version to its cee'd and cee'd SW line-ups.

First launched this year on the pro_cee'd three-door hatchback, the '4' extends Kia's trim naming structure and, of course, sits above the existing '1', '2' and '3' versions.

Both the cee'd '4' family hatchback and cee'd SW '4' family estate car share the same 1.6-litre CRDi turbodiesel engine that produces 126bhp at 4,000rpm - up from 113bhp on other trim versions - and 188lb/ft torque (255Nm) from 1,900 to 2,750rpm.

A six-speed manual transmission is standard and a 4-speed automatic transmission is available as an option on the cee'd SW '4'.

Top speed on both manual variants is 122mph with 0-60mph taking 10.6 seconds in the hatchback and an additional 0.2 seconds in the estate.

CO2 emissions for the cee'd '4' are 119 g/km, placing it in VED band 'C', whilst the combined-cycle fuel consumption figure is an economical 62.8mpg.

Designed to look more sporting, 17-inch alloy wheels, black bezel headlights and rear window privacy glass has been added. The side indicator repeaters have been integrated into the door mirrors.

On the inside there is a full black leather upholstery and front heated seats, and a leather trimmed steering wheel and gear-knob. There is cruise control, with steering wheel mounted controls, and electrically-operated heated and folding door mirrors. A seven-inch colour touch screen system acts as the infotainment hub and controls a fully-integrated colour satellite navigation system - with European mapping - as well as the radio, CD player, iPod connectivity and Bluetooth hands-free systems. In addition, an advanced parking camera system offers a colour view of obstacles to the rear of the vehicle and is displayed on the same screen.

The cee'd SW version adds audible reverse parking sensors to this list.

The cee'd '4' and cee'd SW '4' are priced at £19,195 and £20,345 respectively on-the-road.

The automatic gearbox option on the cee'd SW is priced at £1,100 whilst the sporty-looking pro_cee'd '4' is also available at £18,995 on-the-road.
