Residual value forecasts from CAP for the all-new Mazda6, which goes on sale in the UK in January 2013, are 7.5% higher than the outgoing model.

Major mpg and CO2 emission improvements across the all-new Mazda6 range due to Skyactiv technology have contributed to the residual value enhancements.

Residual value predictions (on a three-year/60,000-mile cycle) for the Mazda6 petrol-engined Saloon range average 31.8%, 33% for the petrol-engined Tourer, 31.6% for the diesel-engined Saloon and 32.7% for the diesel-engined Tourer.

Versus the current Mazda6, those figures represent an average uplift of 7.5% (petrol-engined Tourer), 7% (petrol-engined hatch as no saloon available), 2.6% (diesel-engined Tourer) and 2.4% (diesel-engined hatch as no saloon available).

Those forecasts, according to CAP, put the new Mazda6 comfortably ahead in the residual value stakes against the likes of the Vauxhall Insignia (average 23%), Ford Mondeo (28%), Volkswagen Passat (29%), Honda Accord (30%) and Toyota Avensis (31%).

Mazda forecasts that its biggest fleet seller in the range will be the 2.2-litre 150ps Skyactiv-D saloon SE-L Nav with a P11D value of £23,140, CO2 emissions of 108g/km and combined cycle fuel economy of 67.3mpg.

CAP predicts that the model will have a three-year/60,000-mile residual value of £7,475 (32%).

In-depth analysis reveals that over three-years/60,000 miles the anticipated best-selling model in the new Mazda6 range will depreciate by £15,665, putting it ahead of rivals such as the BMW 320d, Audi A4, Toyota Avensis, Honda Accord and Vauxhall Insignia.

The top-selling diesel Tourer in the all-new Mazda6 range is predicted to be the 2.2-litre 150ps SE-L Nav, which has CO2 emissions of 116g/km and combined cycle fuel economy of 64.2mpg. The model, with a P11D value of £23,890, is forecast to have a residual value of £7,975 (33%) at three years/60,000 miles.

Jeff Knight, editor of Monitor- CAP's residual value forecast guide, said: "Like the recently launched Mazda CX-5 the Mazda6 has been built around the manufacturer's Skyactiv technology.

“This enables the 150ps diesel engine to deliver a CO2 figure for the Saloon of 108g/km placing it at least one company car benefit-in-kind tax band below virtually all the competition.

"However, CO2 emission performance and mpg  is also critical for the used car market in respect of petrol engine cars, as buyers have a greater affinity to such models than the fleet market hence the greater residual value uplift.

"Together with high levels of specification, a more premium interior and excellent future residual values, the all-new Mazda6 should win a place at the front and centre of company car choice lists."

Steve Tomlinson, head of fleet at Mazda, said: "Residual value forecasts for the all-new Mazda6 put the model ahead of key rivals from volume marques and enables the car to close in on premium badge models, which is what we hoped.”
