The entry-level 118bhp 1.8-litre petrol is up to the job and temptingly priced, although Mazda also offers 153bhp 2.0-litre and 168bhp 2.5-litre petrols for those who want a bit more power. Three 2.2-litre turbodiesels with outputs of 127bhp, 161bhp (our favourite) and 177bhp round off the range.
The 6 is a big car, but doesn't feel it because it's agile and grippy, with steering that's light, yet precise at speed. The ride isn't as well-sorted as that of a Ford Mondeo, but it isn't at all uncomfortable.
The 6 is generally a relaxed and quiet cruiser, but refinement isn't class-leading. You notice a bit of wind noise from around the door mirrors and there's some road noise over rough surfaces. You need to be precise with the gearshift, too, but the engines – petrol and diesel – are all smooth and quiet.
All Mazda 6s are exceptionally good on CO2 output, so they're good on company car tax. Your fleet manager will also be keen because leasing rates are attractive. Competitive pricing, good fuel economy and strong resale values make it an appealing private buy.
The interior is something of a mixed bag. It all looks stylish and hardwearing, but some of the materials feel cheap to the touch. That said, in the 2011 JD Power survey, owners praised the quality of the previous-generation car's build and rated the reliability as above average.
Every 6 comes with six airbags, including full-length curtain 'bags. There are also daytime-running lights, anti-lock brakes with electronic assistance and a combination of stability and traction control. Deadlocks and a top-notch alarm make life difficult for thieves.
The 6's cabin has a sporty feel thanks to circular air vents, cowled dials and splashes of metallic trim. The dash is, for the most part, user-friendly, although it's a pity that the stereo and heater controls are separated from the panel that displays their settings. Forward vision is good and there’s a wide range of adjustment on both the driver's seat and steering wheel.
There's plenty of room up front, rear legroom is impressive and, despite the 6's sleek shape, headroom is competitive for the class. The boot is big and square, and the rear seats are easy to fold flat because the bases automatically drop when you lower the backrests.
Even entry-level models have air-con, a CD player with MP3 connection and electric windows. TS trim brings alloys, cruise control, a multifunction steering wheel, electric heated mirrors and dual-zone climate control, while the TS2 adds automatic lights and wipers, front foglights and Bluetooth. Next up is Sport, which has big wheels, a CD changer, xenon headlights and an uprated stereo.
