Editing Challenger 2 (section)

=== Challenger 2E ===
The Challenger 2E is an export version of the tank. It has a new integrated weapon control and battlefield management system, which includes a gyrostabilised panoramic SAGEM MVS 580-day/thermal sight for the commander and SAGEM SAVAN 15 gyrostabilised day/thermal sight for the gunner, both with eye-safe laser rangefinder. This allows hunter/killer operations with a common engagement sequence. An optional servo-controlled overhead weapons platform can be slaved to the commander's sight to allow operation independent from the turret.

The power pack has been replaced by a new {{convert|1500|hp|kW|abbr=on}} [[EuroPowerPack]] with a transversely mounted [[MTU Friedrichshafen|MTU]] MT883 diesel engine coupled to [[Renk]] HSWL 295TM automatic transmission. The increase in both vehicle performance and durability is significant. The smaller volume but more powerful EuroPowerPack additionally incorporates as standard a cooling system and air intake filtration system proved in desert use.

The free space in the hull is available for ammunition stowage or for fuel, increasing the vehicle's range to {{convert|550|km|abbr=on}}. This power pack was previously installed on the French Leclerc tanks delivered to the UAE as well as the recovery tank version of the Leclerc in service with the French Army. Further developed versions of the EuroPowerPack have more recently been installed in the latest serial produced Korean [[K2 Black Panther]] tank.

BAES announced in 2005 that development and export marketing of 2E would stop. This has been linked by the media to the failure of the 2E to be selected for the [[Hellenic Army]] in 2002, a competition won by the [[Leopard 2]].<ref>{{cite web |url=http://www.janes.com/defence/land_forces/news/jdi/jdi050518_1_n.shtml |title=Challenger nears end of the line |publisher=Jane's Land Forces News |archive-url=https://web.archive.org/web/20070214142612/http://www.janes.com/defence/land_forces/news/jdi/jdi050518_1_n.shtml |archive-date=14 February 2007}}</ref>
