2012 Chevy Cruze | Powertrain & Chassis | Chevrolet
fueleconomy.gov rates the NA engine at 22 mpg city & 35 highway = 27 mpg combined. The turbocharged engine is rated at 26 mpg city & 38 highway = 30 mpg combined--a 10% improvement in FE.
Compare Side-by-Side
The Dodge Dart is very similar--two engines with the same exact 160 hp power rating: 1.4L turbo & 2.0 L NA ( 2013 Dodge Dart | All New compact that's everything but compact | Dodge). The 1.4L turbo beats the 2.0L NA engine by 10% ( Compare Side-by-Side).
Research the EPA test procedure--there's a whole lot more to it than just driving around easily in a loop. |
Well thats why i'm assuming the saab LPT tech is worth emulating elsewhere... i'm just wondering if 0psi wastegate options or total bypasses were worth pursuing too.
For EPA the city is more of a struggle, but isnt the highway a steady state 65mph or 70mph now?
