The vehicle features numerous technologies to reduce carbon emissions, such as a catalyzed diesel particulate filter and a variable-geometry turbocharger.

In 2008, Project Kahn, famous for tuning luxury and sports cars, presented a modified Rexton 270 SPR at the 2008 British International Motor Show.

It features added kit, chrome highlights and a "sportier" interior, but unusually, in the initial models, it does not have a radio/CD player, as it is intended that those that potential customers would want to put their own sound system in.

However, the R-Line later gained a Kenwood double-DIN touch screen navigation system with steering wheel-mounted controls.

The R-Line also has a more powerful version of the 2.7-liter straight-five turbo diesel engine producing 186 PS (137 kW) and 402 N⋅m (296 lb⋅ft) torque at 2400 rpm.

At the end of 2015, SsangYong introduced to the European market the 2.2-liter e-XDi diesel engine with Euro 6 compliance.

However, SsangYong chose not to sue SG Automotive, citing China's lawsuit system which is favorable to their companies.

[25] Mahindra revealed a rebadged version of the 2nd generation Rexton called the Alturas G4 at the 2018 Auto Expo, India.

[26] During its lifespan, it was offered in both 2WD and 4WD drivetrains and it was the flagship model of the brand until it was discontinued in late 2022 due to poor sales and marketing.
