DE18LA (M271Evo, 271.8XX) This is the last version of M271 engine family. Dimensions are the same as E18ML and DE18ML, but the supercharger has been replaced with a turbocharger; like the DE18ML it uses the CGI (Stratified Charged Gasoline Injection) gasoline direct injection. Output ranges from 156 PS (115 kW) at 5200 rpm to 204 PS (150 kW) at 5500 rpm. Applications: 2009 Mercedes-Benz C-Class (W204) C 180 CGI, C 200 CGI, C 250 CGI 2009 Mercedes-Benz E-Class (W212) E 200 CGI, E 250 CGI 2009 Mercedes-Benz E-Class Coupé (C207) E 250 CGI C 200 CGI 2011-2014 1,796 cc (110 cu in) 16V I4 turbo (M 271 DE 18 AL) 184 PS (135 kW; 181 hp)@5250, 270 N·m (199 lb·ft)@1800 C 250 CGI 2011-2015 1,796 cc (110 cu in) 16V I4 turbo (M 271 DE 18 AL) 204 PS (150 kW; 201 hp)@5500, 310 N·m (229 lb·ft)@2000-4300 The CGI engines are turbocharged unlike the earlier indirect injection Kompressor engines. They are the same displacement so I imagine the difference is in engine mapping= turbo boost and injection [ possibly slightly larger injectors/turbo ??] It would probably be fairly easy to increase the C200 to near C250 levels with a remap.
