In a bid to boost dismal sales, Renault Samsung Motors will launch a revamped SM3 model, adding exterior and interior features aimed at youthful buyers and a more powerful but fuel-efficient drivetrain combination.

The vehicle was shown to news media in Korea on Wednesday and will hit dealers Sept. 1.

“Based on the globally renowned technology of the Renault-Nissan alliance, the new SM3, which offers excellent fuel economy, refined and urban design, unique quality and innovative digital appeal, will position itself as Korea’s best premium sub-mid sedan in the second half by offering a whole new standard in the domestic sub-mid car market,” RSM’s CEO Francois Provost says in a statement.

Powered by the Renault-Nissan Alliance H4Mk 1.6L Dual CVTC engine, the drivetrain incorporates its new Xtronic continuously variable transmission with an additional auxiliary gear, which RSM says is a world first.

The engine develops 117 hp at 6,000 rpm and torque of 116 lb.-ft. (157 Nm) at 4,000 rpm.

RSM says the New SM3 has the best fuel economy in its class, rated 31/42 mpg (7.6-5.6 L/100 km) city/highway.

The new front end treatment includes an upper mesh-type grill and divided lower grill chrome enhancement, large bumper area and black bezel headlamps.

Hoping to hook youthful buyers, the revamped SM3 features a new dynamic color high-tech instrument cluster. Upon ignition the tachometer-, fuel- and temperature-gauge needles wag up and down as a form of animated greeting.

Prices rise about 1 million won ($881) per vehicle based on all trim levels, ranging from 15.4 million to 19.8 million won ($13,575 to $17,456) in Korea.

The New SM3 will continue to be sold in 86 export markets as the Renault Fluence.
