Peugeot will replace its fleet and family car, the 407, with the elegant 508 in April or May next year. Saloon and estate (SW) versions will go on sale simultaneously.
Both will offer new fuel-saving technologies, including a unique diesel-electric hybrid powertrain (HYbrid 4), which is also destined to appear in the 3008 crossover and possibly the RC-Z coupe.
HYbrid 4 has a diesel engine to drive the front wheels and an electric motor powering the rears, giving the car all-wheel-drive capability. Peugeot says CO2 emissions will be officially rated at 99g/km, making the car exempt from road tax.
What we don't yet know is what rate of company car tax it will attract: petrol-electric hybrids are taxed at 10% of list price, but diesels normally get a 3% loading over comparable petrol engines, so the hybrid 508 could be rated at 13%. Even the Government's revenue and customs department couldn't tell us how the HYbrid 4 508 will be rated.
Peugeot's HDI diesels and the turbocharged petrol engines developed with BMW will appear in the rest of the range, and there will be a new engine stop-start system, called e-HDI, which is said to be quicker in operation than the current one, improving driveability in traffic. Aerodynamics and weight-saving also play a big part in the 508's overall efficiency, Peugeot claims.
