WFEL and Rheinmetall BAE Systems Land (RBSL) have each selected Rolls Royce Solutions UK to supply their MTU engine for the British Army's new Boxer Armored vehicles. 

The MTU 8v 199 TS21 engines are proven in military applications. With a power output of 600kw, the engines allow for enhanced operational mobility and agility and a higher electrical load. The Boxers for the British Army will be the first versions of the vehicle equipped with this engine variant, delivering 70 KW more power than the MTU engines in previous versions of the Boxer.
