L-C had some very subtle suspension mods done to improve the handling, and yes it does handle better than an Omega, despite controlling an extra 150 bhp.
It's the typical Lotus stuff that lets it down, coolant circulation and fuel injection for example, where they went totally off the radar.
In comparison, the V8 engined cars are totally different, feeling completely solid to drive.
coolant circulation or fuel injection are not typical lotus stuff, Lotus's reputation was/is how a car handles and always has been how it goes was an after thought.
Colin Chapman was the greatest car Technician of our time his motto was always speed through lightness and handling was more important to him than outright speed.
the lotus carlton/omega was a masterclass on the princapals of that mantra deverstating in the right hands and enviroments docile at all other times with predictable handling even on the limits.
Having owned both a lotus carlton and lotus omega
both right hand drive for some 60,000 miles conbined i never had fuel inj or coolant problems even after 160 mph autoban cruises.
