"Defender 90" or "Defender 110". The most recent model, from 2007–2016, still featured the space above the radiator for the badge but was blank. Instead it had "Land Rover" spelled across the leading edge of the bonnet in raised individual letters, in keeping with the Discovery and Freelander. At the rear was a new style of '"Defender" badge with an underlining "swoosh". On these last models there are no badges defining the wheelbase model of the vehicle. The wheelbase Land Rover 127, available from 1985, was always marketed with the name rendered numerically. Following the adoption of the Defender name, it became the "Defender 130", although the wheelbase remained unchanged. The North American Specification (NAS) Defender 110 sold for the 1993 model year carried a badge above the radiator grille which read "Defender", whereas the NAS Defender 90 sold for the 1994 to 1997 model years had "Land Rover" spelled across the top of the radiator grille in individual letter decals. NAS Defenders also carried a cast plaque on the rear tub in the original style of the Series estate cars with "Defender 110" or "Defender 90" below the Land Rover lozenge and the vehicle's unique limited edition production run number. Land Rover 90 and 110 Production of the model now known as the Defender began in 1983 as the Land Rover 110, a name which reflected the length of the wheelbase. The Land Rover 90, with wheelbase, and Land Rover 127, with wheelbase, soon followed. Superficially there is little to distinguish the post-1983 vehicles from the Series III Land Rover. A full-length bonnet, revised grille, plus the fitting of wheel arch extensions to cover wider-track axles are the most noticeable changes. Initially the conservative engineering department insisted that the Land Rover was also available with a part-time 4WD system familiar to derivatives produced since 1949. However, the part-time system failed to sell and was quickly dropped from the options list by 1984. While the engine and other body panels carried over from the Series III, mechanically the 90 and 110 were modernised, including: Coil springs, offering a more compliant ride and improved axle articulation A permanent four-wheel-drive system derived from the Range Rover, featuring a two-speed transfer gearbox with a lockable centre differential A modernised interior A taller one-piece windscreen A new series of progressively more powerful and modern engines The 110 was launched in 1983, and the 90
