Large sedans don't usually have small engines, but CO2 emissions limits and taxes have given automakers incentive to launch green versions of their larger models. Think of the Citroën C5 Airdream, the Opel Insignia Ecoflex or the VW Passat Bluemotion. Now we can add Škoda, a brand that belongs to the Volkswagen group, and its Superb Greenline to the list. Mated to the same engine as the Passat, a 1.9 TDI PD diese that is good for 105 hp, 46 mpg U.S. (5.1 l/100 km) and CO2 emission levels of 136 g/km. The Superb isn't small; in fact, it's larger than an Audi A6. The Green Line model has lost a bit of weight and gets longer gears, a remapping of the engine for improved efficiency, improved aerodynamics and low-rolling resistance tires. Prices start at £16,710 in the UK.
