The entry-level 118bhp 1.8-litre petrol is up to the job and temptingly priced, although Mazda also offers 145bhp 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 123bhp, 161bhp (our favourite) and 182bhp 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 trade-off for this agility is a firm-ish ride, but it stops short of being uncomfortable. We'd describe it as informative rather than annoying.
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 – the passenger gets dense, cushioned plastics, while the driver makes do with harder stuff. That said, Mazdas don't tend to go wrong and consistently score well in the JD Power customer satisfaction survey.
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 S models have air-con, a CD player, four electric windows and alloy wheels. Upgrading to TS trim brings cruise control, a multifunction steering wheel and dual-zone climate control, while the TS2 adds automatic headlights, Bluetooth connectivity and a CD changer. Next up is Sport, which has big wheels and a bodykit. Then at the very top end there's the Sports Luxury, with full leather trim and front and rear parking sensors.
