The Honda Integra DC5 is a Japanese vehicle, which was also known as the Acura RSX in North America and Hong Kong. It is available in base and "Type-S" trim levels in North America, and a "Integra iS / Integra Type S" and "Type R" version sold in Japan and Oceania. However, to add to the confusion, the "Type R" sold in Oceania is very similar to the "Type-S" sold in North America, and the Integra line naming in Oceania have recently been realigned so it's similar to North America conventions. Canada had three models: Base (cloth interior, no sunroof, steel wheels with wheel covers), Premium (leather interior, sunroof, alloy wheels) and Type S. In other places, (eg. Hong Kong, Singapore, Australia) only the base version is available.

Engineering and design


When designing the Integra, Honda chose to base it on an entirely new platform, rather than incrementally re-engineering the previous Integra/Civic platform. This new chassis would also be shared with the 2001 Civic. This was a significant change from the previous 1998 revision of the Integra, which had only been a minor refresh. In addition, this platform was the first entirely new entry-level chassis Honda had debuted since 1994. Owing to its more capable and luxurious nature, the Acura division chose to market the vehicle as the Integra's replacement, and badged it as the RSX. Touting the vehicle's more upscale feature-set and more luxurious amenities, Acura hoped to use the RSX to help garner more brand recognition and respect from older, wealthier buyers who tended to see the company's offerings, especially the Integra, as sporty and reliable, but not as mature or luxurious. Outside of North America, where the Acura division did not exist at the time, Honda chose to continue selling the model as the Integra, and continued to aim the car at younger men who wanted something more upscale than a Civic Si without having to spend considerably more money.

The Integra suspension employs MacPherson strut in the front and Double-wishbone suspension in the rear. This engineering decision disappointed some Honda enthusiasts who had come to appreciate Honda's philosophy of employing double-wishbones for both front and rear suspensions. However, the K-series engine proved to have significant potential for tuning, a trait shared with the B-series engines previously employed in Integra and certain performance-oriented Civic models. The K-series engine features intelligent VTEC or (i-VTEC), which electronically adjusts valve lift, valve duration and valve timing, giving the 2.0 L Car engine a flatter torque curve relative to previous VTEC implementations which only adjusted valve lift and valve duration.

The base Integra has the K20A3 motor with an output of 160 hp (119 kW) and is offered with either an automatic or a five-speed Manual transmission; the Type-S has a 200 hp (2002-2004) K20A2 or 210 hp (157 kW) in 2005 K20Z1 motor and a short-throw 6-speed Manual transmission. For the 2006 model year vehicles Honda switched to the Rev 8/04 SAE standards for measuring hp. The base RSX for 2006 was rated at Convert/hp and the Type-S was rated at Convert/hp. In 2005 the RSX Type-S received camshafts, b-pipe and muffler, 4.77 final drive ratio, crankshaft pulley and the intake snorkel duct from the Japan model Honda Integra Type-R. The rev-limit was also increased from 8100 rpm to 8300 rpm. Another major change made to the inline VTEC-i engine was the use of a timing chain rather than a timing belt, which reduced maintenance needs.

The Honda Integra Type-R, sold in Japan, Australia, and some other markets, has reduced weight, a 220 PS / 164 kW / Convert/hp K20A Straight-4 engine (Japan-only; Oceania models have an engine similar to the Acura RSX-S), as well as a Limited slip differential (LSD) and stiffer springs and shocks, 4 piston Brembo brakes, 17" wheels on Bridgestone Potenza tires, Recaro suede seats, body trim, and more. The IIHS did not rate the RSX.

Replacement


Although it had been a strong seller for Honda, the RSX did not fit within the confines of Acura's re-structured market strategy, formulated after the decision to take the Acura brand worldwide (previously, the Acura nameplate has appeared only in North America, elsewhere in the world the same models are sold as Hondas). With the introduction of the similarly powerful and less expensive 2006 model-year Honda Civic Si to the marketplace, the decision was made to discontinue production of the RSX, with the final units built in summer 2006. Because of its lower pricing and longer list of available options, Honda considered the new Civic Si to be a more viable choice for performance minded young men, who were the most common buyers of RSXs. The TSX would replace the Acura RSX as Acura's entry level nameplate starting in 2007[1].
