of annual road tax. In September 1975, in order to meet the new emissions regulations for that year, the L26 was replaced by the larger yet 2753 cc L28 six-cylinder. By October the carburettors in the L20 were replaced with electronic fuel injection and the engine was now dubbed L20E. Because of the difficulty in meeting the emissions regulations, the twin-carburetted engines were all discontinued. The 1,770 cc L18 replaced the G18 in the lineup. In February 1976 carburetted 1.8-litre and 2.0-litre engines which met the 1976 emissions regulations were introduced, and were identified with the Nissan NAPS badge. Laurel C130-EV In 1974 Nissan developed an electric passenger sedan based on the Nissan Laurel. The Nissan Laurel C130-EV - referred to as the Datsun 200L-EV in export markets - developed to be used by the VIPs at the 1975 International Oceanographic Exposition in Okinawa. It was originally engineered by the Prince Motor Company, but produced by Nissan when the company assumed Prince operations in 1966. The C130-EV uses one electric motor, rear-mounted and driving the rear axle through a two-speed automatic transmission. The Nissan Laurel C130-EV has a claimed top speed of and a range of . Nissan's next electric car venture would be the 1998 Altra. Third generation (C230; 1977–1980) The third generation appeared in January 1977. For the first time, the C230 was available in either saloon and hardtop coupé form, but also as a hardtop saloon without B-posts. The hardtop was only available with six-cylinder engines. Buyers could choose between a 1.8-litre four, a 2.0-litre inline-six (carburetted or fuel-injected, a first for the Laurel), a 2.8-litre six, or a 2.0-litre diesel four, sourced from Nissan Diesel as an alternative to the diesel-powered Toyota Mark II and the Isuzu Florian. Transmissions were mainly four- or five-speed manuals or a three-speed automatic, although a three-speed manual with a column shift was also available in the lower spec and commercial versions. In the autumn of 1978 the C230 received a mild facelift (type C231), marked visually by squared instead of round double headlights. The Toyota competitor was the Mark II coupé and sedan. Again, comfort was prioritized over handling and agility. One year later (January 1978) Nissan released a tenth anniversary edition, which adopted a special deep red body color known as "Laurel's Crimson", as well as trim-specific emblems, aluminum wheels and front grille. In 1979 the 2.4-litre L24 engine
