The Honda Integra DC5 (Japanese: ホンダ インテグラ DC5) is a Japanese performance car, which was also known as the Acura RSX (short for Rally Sportscar eXperimental) in North America. It is available in base and "Type-S" models in North America, and a "Integra iS / Integra Type S" and "Type R" version sold in Japan and Oceania. However, the "Type R" sold in Oceania is very similar to the "Type-S" sold in North America, and the Integra line naming in Oceania has recently been realigned to be similar with North American 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, (e.g. Hong Kong, Singapore) only the base version is available.

The Integra suspension employs MacPherson struts 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 engine a flatter torque curve relative to previous VTEC implementations which only adjusted valve lift and valve duration. All RSX's have timing chains, instead of belts, which reduces maintenance required.

The base RSX has the K20A3 engine with an output of 160 hp (120 kW) and is offered with either an automatic or a five-speed manual transmission; the Type-S has a 200 hp (150 kW) (2002–2004) K20A2 or 210 hp (160 kW) in 2005-2006 K20Z1 engine and a short-throw 6-speed manual transmission. In 2005 the RSX Type-S received camshafts, b-pipe and muffler, 4.7 final drive ratio, crankshaft pulley and the intake snorkel duct from the Japanese model Honda Integra Type-R.

The Honda Integra Type-R, sold in Japan has reduced weight, a 220 PS / 164 kW / 217 hp (162 kW) K20A I4 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.

This model is the final generation of the Honda Integra; afterwards production ceased.

Replacement Edit

Although it had been a relatively 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. The last one rolled off the assembly line on July 7, 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(or women), who were the most common buyers of RSXs. The TSX would replace the Acura RSX as Acura's entry level nameplate starting in 2007.

Awards Edit

Racing Edit

Acura won the Manufacturers' Championship of the SCCA World Challenge Touring Car class in 2006, running both RSXs and TSXs. RSX drivers finished in 5th and 9th in the Drivers' Championship.[3] Kensai Racing is using RSXs and TSXs in the KONI Challenge Series.[4] Badged as a Honda, the DC5 won the British Touring Car Championship with Matt Neal in 2005 and 2006, for Team Dynamics (branded as Team Halfords after the title sponsor). The racing community has embraced the RSX enthusiastically. Both A2 and A3 versions of the K20 motor have shown a major potential for tuning and surprising durability when exposed to extreme conditions under aftermarket forced induction applications which in recent years became very popular and vastly available among car enthusiasts.


Driver deaths fatality risks statistics — published by the IIHS — rated the RSX and 15 other vehicles among the "Highest rates of driver deaths.", The RSX had 202 driver deaths per million registered vehicle deaths, while the average for the RSX class (2-door small) was 134. Other small cars on the list included the Kia Spectra hatchback (191), Pontiac Sunfire (179), Mitsubishi Eclipse (169), Dodge Neon (161), and the Chevrolet Cavalier 4dr (150).[5]
