Mighty Muscular Hummer H3

The very powerful and the brand new the Hummer H3 has made its mark among all its rivals.
The H3 was launched with a 3.5 liter straight-5 cylinder L52 engine that produced 220 hp (160 kW) and 225 lbf·ft (305 N·m) of torque and was mated to a standard five-speed manual transmission or an optional Hydra-Matic 4L60-E four-speed automatic transmission. In 2007 this engine was replaced by 3.7 liter LLR that produced 242 hp (180 kW) and 242 lbf·ft (328 N·m) of torque, figures that were revised in 2009 to 239 hp (178 kW) and 241 lbf·ft (327 N·m). Under revised EPA testing standards when equipped with either transmission this straight-5 engine achieved 14 mpg-US (17 l/100 km) in the city and 18 mpg-US (13 l/100 km) on the highway with a combined average of 15 mpg-US
(16 l/100 km). Available solely with the automatic transmission, a 5.3 liter LH8 V8 engine producing 300 hp (220 kW) and 320 lbf·ft (430 N·m) of torque was added in 2008 for the Alpha model and delivered slightly lower fuel economy, estimated at 13 mpg-US (18 l/100 km) in the city, 16 mpg-US (15 l/100 km) on the highway, with a combined average of 14 mpg-US (17 l/100 km).
