context_page_description: The Chevrolet Corvette (C4) is a sports car produced by American automobile manufacturer Chevrolet from 1983 to 1996. The convertible returned, as did higher performance engines, exemplified by the 375 hp LT5 found in the ZR-1. In early March 1990, the ZR-1 would set a new record for the highest 24 hour-5,000 mile land-speed by going over a speed of 175 mph. Prices rose and sales declined, in spite of a completely new chassis, modern sleeker styling, and other improvements to the model. The last C4 was produced on June 20, 1996.
context_section_description: Also called 'Big Dog', the ZR2 is a concept model based on a C4 Corvette, but with a much larger 7.4 L (454 cu in) big block OHV V8 engine with multi-port fuel injection similar to the tuned port injection found on the 1985-1991 base model and a 6-speed manual transmission.
  The vehicle was built by Corvette Development Engineering as a development car to study the possibility of achieving the performance of the ZR-1 while reducing cost by utilizing a big block engine. The engine was rated at 400 hp (406 PS; 298 kW).
  The prototype vehicle was sold in 2009 at the Barrett-Jackson Collector Car Auction for US$65,000.
