An attractive vehicle for car leasing customers is the Vauxhall Insignia Ecoflex. Its a frugal version of the companies new project and has some impressive statistics to go with it. The Ecoflex version is capable of just under 55mpg and emits just 136g/km of CO2 making it a good choice for many motorists. The car uses a slightly detuned version of the 2.0-litre diesel, which has a 0-60 speed of under 9 seconds and can reach 135mph. It has had its ride height reduced by 10mm to lower its drag coefficient to 0.26 making it as aerodynamic as the Toyota Prius but a lot better looking with it!
