Honda Civic HF
From Honda press: The all-new 2012 Honda Civic represents the ninth generation of one of the company's most popular and globally recognized products. Having earned a reputation for being a fun-to-drive compact that is simultaneously fuel efficient, sporty, stylish and durable, the Civic has become a beloved and relied-upon member of the worldwide transportation family. Cumulatively, the Civic has reached 8.8 million customers in the United States through 2010 since its launch as a 1973 model.
Each generation of Civic has improved with a specific development theme in mind. The 2012 Civic embraces the fundamental concept of a “futuristic and distinctive compact,” a direction that introduces new values that reach ahead of present-day needs and elevates the experience that Civic represents. Major strides include improvements to refinement throughout, increased fuel economy on all models, the further addition of interactive technologies for personalization and convenience, along with enhancements to performance, ride and interior packaging.
The Civic Sedan, Civic Coupe, Civic HF and Civic Natural Gas benefit from an updated and refined version of the 1.8-liter I-4 engine that powered the previous generation Civic. The new engine has extensive changes that reduce friction, improve emissions performance and increase fuel economy.
The engine is a Single Overhead Cam (SOHC) 1.8-liter inline 4-cylinder design with 16 valves, i-VTEC®, and a dual-stage intake manifold. In the Civic Sedan, Civic Coupe and Civic HF, the engine produces 140 horsepower at 6300 rpm, and 128 lb-ft. of torque at 4300 rpm. In the Civic Sedan and Coupe, the 1.8-liter engine has an estimated* EPA city/highway fuel economy rating of 28/39 miles per gallon when equipped with automatic transmission.
This same powertrain in the Civic HF achieves a higher estimated city/highway fuel economy rating of 29/41 miles per gallon with its standard 5-speed automatic transmission, primarily due to reductions in aerodynamic drag and rolling resistance. With a version of the same 1.8-liter engine, the Civic Natural Gas powertrain develops 110 horsepower and 106 lb-ft of torque.
