Passing Euro 5 emission standards means the car can be sold in the European Union member states. Euro 5 standards were introduced in 2008/2009 and won't be increased or outdated until 2014 when the Euro 6 standards come into play. The standards are, in a nutshell, an accepted amount of emissions allowed to exit the exhaust of a given vehicle.
Minor changes to the car's exhaust system and engine mapping were made to meet the standards. Sources say the car will still be able to offer the same performance levels, such as doing the 0-100km/h sprint in under five seconds.
The new car will also get slight revisions to the interior including a centrally-mounted rev tacho, improved side-bolster seating in the front as well as minor trimming changes with dark silver inserts.
