2004, the fifth generation of the Titan was launched, built by Isuzu (see below). The Titan (from 1.5- to 4-ton payload) became a rebadged Isuzu Elf. The 1-ton Titan Dash remained in production. In December, the Diesel versions adopted the Bongo's DPF-equipped 2.0 litre turbo-diesel engine, in order to meet new short-term emission regulations. A driver's seat airbag became standard equipment across the Titan Dash range. In August 2007, Diesel versions became compliant with the new long-term emission regulations for compact vans and trucks with a loading capacity of 1 ton or less, due to changes in the compression ratio and DPF capacity. The Titan Dash was discontinued in 2010. Fifth generation (2004–2007) In June 2004, the lighter Titan Dash became the only truck to be built in-house by Mazda, as the fifth generation Titan was an OEM-supplied Isuzu Elf. The fourth generation Titan was the last 1.5-4t truck developed by Mazda, and saw an uncommonly short production run of only four years - the production life of a truck in the Japanese market usually being around 10 years. The Isuzu-built Titan featured three Diesel options, 3.1 L, 4.8 L and 4.8 L turbo, in addition to LPG and CNG engines. 4-wheel drive versions and crew cabs were now also available. Sixth generation (2007–present) In January 2007, the sixth generation of the Titan was launched for the Japanese market featuring a newly designed body, Mazda's auto start-stop system, a new range of engines and lighter body panels. The target sales volume was limited to 430 units per month. References Titan Trucks
