The most furious Opel I have traveled to the Opel city of Rüsselsheim with the very purpose of visiting the hallowed halls of Opel Classic. In the premises here resides a unique collection of some of the finest Opel models of all time. This is also where they are maintained and repaired if necessary. The car I have on my to-do list today is the legendary Opel Lotus Omega, which was also called the Vauxhall Lotus Carlton when it was sold in the UK. Although there are several cool variants of the so-called Omega A in the form of the sporty Omega 3000 or the rare homologation car called the EVO 500, the Lotus Omega is the most edgy Opel of them all. The heart – a 3.6-liter inline six! However, there are not many Opel emblems fitted, as many of them have instead been replaced with the yellow and green logo of the British sports car brand Lotus. When the car was developed in the late 80s, both Opel and Lotus were owned by the American car group GM. The potent Omega is therefore also in many ways a collection of mechanical greatest hits from the group's many brands. Under the hood's open gills is a 3.6-liter biturbo engine with six cylinders in a row, which produces 377 hp and 557 Nm. The engine is based on Opel's then 3-litre straight-six, which can be traced back to the 70s, when it was fitted with carburettors and started serving in the Monza and Senator models.
