    Mercedes is finally responding the BMW’s lead in reducing CO2 emissions with the introduction of three new fuel-efficient C-class models at the Geneva show. Dubbed “Blue Efficiency”, they use clever technology to dramatically cut fuel consumption and emissions. Both petrol and diesel versions will get the “Blue Efficiency” treatment; the C180 Kompressor, C350 CGI and C200 CDI.
   
   Most impressive of all is the C200 CDI Blue Efficiency. Powered by Mercedes-Benz’s 2.2-litre four-cylinder common rail diesel with 134bhp and 199lb ft of torque, it boasts combined average fuel consumption of 55.4mpg and a CO2 rating that betters many superminis at 135g/km (standard model: 46.3mpg and 149g/km) while possessing 0-62mph acceleration in 10.4sec and a 137mph top speed.
   
   Weight has been saved with a thinner windscreen, less sound deadening equipment and thinner, lighter alloy wheels shod with low rolling resistance tyres. The co-efficient of drag has been trimmed from 0.27 to 0.25 by blanking off part of the grille, sealing the joints around the headlamps and fitting more aerodynamic door mirrors.
