Honda Civic Sedan
From Honda press: The 2006 Civic represents an extreme transformation of design and dynamics. Multiple powertrains for 2006 range from 197-horsepower (2) high performance to 51 mpg gas-sipping hybrid to an all-around performer with two body styles, representing one of the most diverse vehicles in the industry. An expressive and futuristic design with exciting performance and a dedication to providing advanced safety technology set the Civic apart from the competition.
The Civic has always offered industry-leading features designed to reward customers with fun-to-drive performance, efficient and environmentally friendly operation and enhanced safety, and the 2006 model goes further than any Civic before it. The first noticeable difference is that both Civic Sedan and Coupe have entirely new dimensions that make each vehicle wider and shorter in height for a sleek, futuristic appearance that also benefits packaging efficiency, handling and ride quality.
The Civic is available with three powertrains that consist of a 197-horsepower, 2.0-liter i-VTEC engine in the Civic Si; a 110-horsepower and ultra-efficient 1.3-liter i-VTEC engine with Integrated Motor Assist in the Civic Hybrid; and an innovative 140-horsepower, 1.8-liter i-VTEC engine in the Civic Sedan and Civic Coupe. The 1.8-liter i-VTEC engine provides off-the-line acceleration performance at low rpm equivalent to that of a 2.0-liter engine, and efficiency that is up to 6 percent better than the current 1.7-liter Civic engine, making it one of the world's most efficient 1.8-liter engine designs. A 6-speed manual transmission with a limited slip differential is standard in the Civic Si, a Continuously Variable Transmission (CVT) is standard in the Civic Hybrid, and the Civic Sedan and Coupe are equipped with a standard 5-speed manual or an available 5-speed automatic transmission.
The Civic Sedan and Civic Coupe benefit from a new generation of Honda engine technology that provides performance similar to a 2.0-liter engine and fuel economy similar to a 1.5-liter engine. The new engine offers significantly improved low rpm torque and top end power. A new 5-speed automatic transmission (available) extracts this extra power to its fullest potential. Additional new Civic technology includes a drive-by-wire throttle control and a dual-stage air intake manifold.
For 2006, all Civic Sedan and Civic Coupe models are powered by a Single Overhead Cam (SOHC) 1.8-liter inline four-cylinder design with 16 valves, a new version of i-VTEC, and a dual-stage intake manifold. The engine produces 140 horsepower @ 6300 rpm (up from 127 horsepower at 6300 rpm, EX trim level), 128 lb-ft. of torque at 4300 rpm (up from 114 lb-ft. @ 4800 rpm, EX trim level) and an estimated EPA city/highway fuel economy of 30/40 miles per gallon (up from 29/38 miles per gallon on LX with automatic transmission). Emissions in all 50 states are rated as ULEV-2, an improvement from the ULEV-1 emission standard on the 2005 model. The engine performance differences are even greater when compared the 2005 Civic's LX and DX trim levels that produced 115 horsepower @ 6100 rpm and 110 lb-ft. of torque @ 4500 rpm.
