The WRC bred Imprezza WRX STI, which makes its UK public debut at Autosport International Show at Birmingham’s NEC in January has been priced at only £24,995 On-The-Road, £1,600 less than old model. The STI is powered by a 300 PS (305 hp) 2.5-liter turbo flat 4-cylinder – unlike the Japanese market STI which uses a higher-revving 2.0-liter turbo. Max speed is 155.3 mph with a 0-60 mph time of 4.8 seconds. Fuel consumption compared to the previous model improves to 20.5/34.4 and 27.4 on the Urban/Extra Urban and Combined Cycles.
