The second LF-A concepts had an overall length of , and a wheelbase of ; height remained the same as the prior concept, while width grew to . While the original LF-A had been strictly a concept model, the second concept's design reflected engineering analysis for possible production. The exterior design had been restyled to take advantage of the flexibility offered by carbon-fibre construction, with improved aerodynamics and surface features aimed at improving the car's overall top speed. The reshaped exterior featured smoother lines with additional detailing, and more curved surfaces. The aft radiator cooling vents were retained, but integrated into the rear fascia, and the lower side and front air intakes were restyled, along with the forward fascia and headlamps. Designers reportedly drew inspiration from the 1965 2000GT sports coupé, which was also produced in a front-engine, rear-wheel drive layout, and represented the combination of Japanese technology and design ethics in a sports car. However, no design features on the LF-A were directly derived from the 2000GT. The second LF-A concept and accompanying LF-A Roadster were also equipped with a retractable rear wing for improved handling at speed and a two-seat interior with a two-tone colour scheme.
