Variable Cylinder Management
Variable Cylinder Management (VCM) is Honda's term for its variable displacement technology, which saves fuel by using the i-VTEC system to disable one bank of cylinders during specific driving conditions—for example, highway driving. The second version of VCM (VCM-2) took this a step further, allowing the engine to go from 6 cylinders, down to 4, and further down to 3 as the computer sees fit. The most recent version of VCM (VCM-3) reverted to the previous 3- and 6-cylinder operation. Unlike the pushrod systems used by DaimlerChrysler's Multi-Displacement System and General Motors' Active Fuel Management, Honda's VCM uses overhead cams. A solenoid unlocks the cam followers on one bank from their respective rockers, so the cam follower floats freely while the valve springs keep the valves closed. The system operates through controlling the flow of hydraulic engine oil pressure to locking mechanisms in the cam followers. The engine's drive by wire throttle allows the engine mana ...

VTEC
VTEC (Variable Valve Timing & Lift Electronic Control) is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM. The VTEC system uses two (or occasionally three) camshaft profiles and hydraulically selects between profiles. It was invented by Honda engineer Ikuo Kajitani. It is distinctly different from standard VVT (variable valve timing) systems which change only the valve timings and do not change the camshaft profile or valve lift in any way. Context and description Japan levies a tax based on engine displacement, and Japanese auto manufacturers have correspondingly focused their research and development efforts toward improving the performance of their smaller engine designs. One method for increasing performance into a static displacement includes forced induction, as with models such as the Toyota Supra and Nissan 300ZX which used t ...

Honda Inspire
The is a mid-size sedan introduced by Honda in 1990 derived from Honda Accord chassis. The first Inspire debuted in 1990 as the Accord Inspire, a sister nameplate to the Honda Vigor, but sold at different retail channels in Japan, known as ''Honda Verno'' for the Vigor/Saber, and the Inspire at ''Honda Clio'' stores. The Inspire was developed during what was known in Japan as the Japanese asset price bubble or "bubble economy". In 1995, the Inspire was updated and exported to the US as the Acura 3.2 TL, while the Vigor nameplate was replaced with the Honda Saber. The longitudinal 2.5 L straight-5 engine layout and platform remained and was sold as the Acura 2.5 TL. In 1999, these cars were replaced by the second generation TL that was based on the US-spec Accord platform, and largely designed and engineered in the US by Honda R&D Americas, Inc. in Raymond, Ohio. Manufactured in the US, these were imported into Japan as the new Inspire and Saber. In June 2003, the fourth gene ...

Acura MDX
The Acura MDX is a mid-size luxury crossover SUV with three-row seating produced by the Japanese automaker Honda under its luxury Acura division since 2000. The alphanumeric moniker stands for "Multi-Dimensional" luxury. It has ranked as the second-best selling mid-size luxury SUV after the Lexus RX. The MDX is the first luxury crossover SUV to have standard third-row seating, and shares its platform with the Honda Pilot. The Pilot was made available with an eight person seating configuration, while the MDX exclusively seats seven, with two seating positions in the third row.

In Japan, it was made to replace the Honda Horizon (also based on the Trooper) which was discontinued in 1999. In 2003, the vehicle went on sale in Japan and Australia as the Honda MDX; sales with Honda badges ended with the introduction of the second generation th ...

Acura RLX
The Acura RLX is a mid-size flagship luxury car manufactured by Honda and sold under their Acura division, released in 2013, succeeding the Acura RL, RL. The RLX was discontinued in 2020. Background and development The Acura Legend was a very successful vehicle to launch Acura as a separate division, and combined with sales of the Acura Integra, Integra this resulted in Acura outselling longtime luxury marques BMW and Mercedes-Benz as well as Toyota's new luxury division Lexus. However, the successor RL sold below expectations due to relatively tight interior for its size, the lack of a V8 performance engine option and better handling rear-wheel drive experience, and/or relatively expensive compared to its rivals. An October 2009 ''Car and Driver'' blog cited a dinner with Acura executives who acknowledged that the introduction of the new, larger, and in some guises, more powerful, fourth generation Acura TL made it difficult to market the then-current RL. In November 2009, an Au ...

Honda Accord
The , also known as the in Japan and China for certain generations, is a series of cars manufactured by Honda since 1976, best known for its four-door sedan variant, which has been one of the best-selling cars in the United States since 1989. The Accord nameplate has been applied to a variety of vehicles worldwide, including coupes, station wagons, hatchbacks and a Honda Crosstour crossover. Since its initiation, Honda has offered several different car body styles and versions of the Accord, and often vehicles marketed under the Accord nameplate concurrently in different regions differ quite substantially. It debuted in 1976, as a compact hatchback, though this style only lasted through 1989, as the lineup was expanded to include a sedan, coupe, and wagon. By the sixth-generation Accord at the end of the 1990s, it evolved into an intermediate vehicle, with one basic platform but with different bodies and proportions to increase its competitiveness against its rivals in diffe ...
