The Acura Vigor was Acura's mid-size sedan sold in the United States from 1992 to 1994, and was replaced by the Acura TL/Honda Saber.
Beginning September 25, 1981, Honda produced a variant of the Honda Accord badged as the Honda Vigor for Japan only. The first generation Vigor was a higher grade 4 door sedan and 3 door hatchback, with the 1.8 L engine as the only engine available. The Vigor was a sportier, faster, "vigorous" Accord with a higher level of equipment over the more sedate Accord. The Vigor competed with the Toyota Corona Mark II and the Nissan Laurel in Japan. This engine debuted the SOHC 3 valve per cylinder mated to a 4 speed automatic transmission with a lock up torque converter. Items that were optional on the Accord, such as cruise control, power windows, and power steering were standard on the Vigor. A trip computer that displayed mileage, driving time, and fuel economy was also standard on the Vigor.
Trim levels that were offered were the VT-i, VTL-i, VXR, VX, VL. PGM-FI fuel injection was standard on the VT-i and VTL-i. The hatchback was available on the TT-i.
June 4, 1985 saw the introduction of the redesigned Vigor as a 4 door sedan only. As before, the Vigor was an uplevel Accord. The 1.8 L B18A engine was now offered with dual carburetors and a larger 2.0 L B20A engine was offered Honda's PGM-FI, with the 1.8 L A18A engine as the basic offering. The Vigor had minor cosmetic differences from the Accord, using a different front grille and rear tail lights. May 1987 saw the introduction of the 2.0 Si Exclusive, adding electric retractable side view mirrors as standard. A automatic shift-lock system was added September 1988 on the "MXL Super Stage" trim level.
At the launch of the fourth generation Accord, the Vigor was no longer based on the Accord chassis. The third generation Vigor was based on the new, longer Honda Inspire and the new Honda Legend. The Vigor was sold in the United States and was badged as the first generation Acura Vigor in 1992. The Honda Inspire was not yet introduced to the USA until the next generation was introduced in 1995, and sold as the Acura 3.2 TL, with the Vigor sold as the Acura 2.5 TL.
