km/h more than the standard SLR). A new suspension is used with 19-inch (480 mm) light-alloy wheels, a stiffer damper configuration and 0.4 inches (10 mm) lower body. In 2007, the Mercedes-Benz McLaren SLR Convertible was announced, which has been available from late 2007. The car uses the same supercharged 5.5 litre V8 that is in the coupé. A limited edition called the SLR Stirling Moss was introduced. The car was the final SLR produced and a tribute to Stirling Moss. Beneath the scissor-doors is a plaque with Moss' signature on it. Unreleased vehicles The partnership between Mercedes-Benz and McLaren resulted in three further cars being proposed. The P9 was to be a mid-engined baby supercar with a less expensive model, with the P8 (or "SLS") competing with cars such as the Ferrari F430, Bentley Continental GT, and Aston Martin DB9. Both cars were to be powered by naturally aspirated V8 engines. The P10 would have been an SLR replacement. All three cars were aborted in 2005, with Mercedes rumoured to have considered the projects simply too costly to turn into a solid business case, although Mercedes' AMG subsidiary produced a flagship sports car called the Mercedes-Benz SLS AMG. The car had a naturally aspirated V8 with over 570 bhp (430 kW; 580 PS); however, it is not thought to be related to the P8 project.
