In August 2004, Audi announced that the next generation TT would be manufactured using aluminium, and would go into production in 2007.[20] A preview of the second-generation TT was provided in the form of the Audi Shooting Brake concept car, shown at the Tokyo Motor Show in 2005. This concept was an insight into the new TT, but featured angular styling, and a "shooting-brake" two-door hatchback body style. Audi debuted the second-generation TT, internal designation Type 8J, on 6 April 2006, using the Volkswagen Group A5 (PQ35) platform with aluminium front bodypanels, and steel in the rear, to enhance its near-neutral front-to-rear weight distribution. Available in front-wheel drive or "quattro" four-wheel drive layout, the TT was again offered as a 2+2 Coupé, and as a two-seater Roadster. The second generation was five inches longer and three inches wider than its predecessor.[22]Factory production commenced during August 2006.
