Following the example of the tradition inherent in certain European brands such as Ferrari, Lamborghini and Porsche, Honda joined in this model work in engineering, the latest technology and high quality construction. With this recipe Honda put on the streets, in 1990, the NSX – sporty two-seater mid-engine and rear-produced almost handcrafted by Japanese brand. His innovations begin with the entire body is aluminum, the same material used in the arms of suspension and the structure of banks. The result is a weight relief of the order of 200kg.
The cab design was inspired by the American F-16 fighter, with an emphasis on broad visibility. The aggressive lines with retractable headlamps, large side air outlets and lanterns that occupy the entire width of the back, are the same since launch and do not seem stale. Only wheels that won new design and an inch more in diameter (15 inches before. Ahead and 16 ago now 16:17 pol.), And front spoiler were modified in 1997. A Ceiling Removable was introduced in the NSX-T (Targa) version, released in 1995, receiving treatment for aerodynamic airflow is diverted passengers Inside sought, rather than space, comfort and ease of use. O, full panel includes voltmeter and oil pressure gauge. The main controls are driving along and there are cruise control and air-conditioning temperature. The seats are upholstered in leather and feature electric adjustment. A system Bose stereo with speakers designed for perfect balance (the nearest occupant does not overlap the farthest), complete the internal atmosphere.
But the best of the NSX lurks under the hood, or rather behind the seats. Besides V6 DOHC and 3.0 273cv (270hp) engine originally released, went from 97 to offer 3.2 of 294cv (290hp) – standard on the North American version, sold under the Acura brand, with manual gearbox (developed in Japan 280CV (276hp) per requirement of the law there). In the name of efficiency, the connecting rods are titanium (Honda patented technology for street cars) and cylinder use a new alloy with aluminum-carbon fiber. The new heart is able to take you from 0 to 100 in six seconds and the speed of 275km/h. The version with automatic transmission keeps the 3-liter engine, a still enough to 260km/h more "gentle" setting 256cv. Despite the increase in displacement, the new engine was still 2.4kg lighter than the old one.
A technical resource launched today the NSX and extended to various Honda models, but that does not lose its appeal, is the VTEC – Variable Valve Timing and Lift Electronic Control, or variable electronic control of time distribution and collection of the valves. Each pair of valves has three rebounds, two "tame" the ends and a more "angry" at the center. At low and medium engine speeds, only the external cams work. From 5,800 rpm, the computer System commands an increase in oil pressure that puts into operation the central cam, modifying the opening and removal of valves. When VTEC joins the VVIS – Variable Volume Induction System, or variable volume intake system – altering the intake manifold, optimizing the torque in low revs and power at high rpm.
The new engine came with a redesigned exhaust system with catalyst ahead (for entry into faster action at low temperatures), and a manual six-speed with rates close together (close ratio) relationships. The course was reduced by 10% and synchronizers are double for the first four gears. The SportShift automatic exchange is also new: it can be operated manually with the steering wheel controls with an electronic control to inhibit changes that may cause excessive speeds.
To transmit all the power to the ground, the limited-slip differential is there and the TCS System – Traction Control System – Traction Control, Switchable by button on the panel. Wheels and tires are wider with the 3.2 liter engine. There were also improvements in brakes with larger discs and revised antilock system, and toward whose assistance is electric and not mechanically connected to the engine. The suspensions remain scheme and upper arms lower triangular.
All this is covered by a warranty of four years or 100,000km.
But few know the Brazilian driver Ayrton Senna helped develop the basic design of the prototype NSX in its test phase. This occurred during the agreement made between the automaker Honda who stood as an engine supplier to McLaren. Ayrton contributed by performing various tests of performance and control during long sessions at Suzuka Circuit.
