Mazda's bread-and-butter 6 looks to be receiving a dramatic makeover for 2008. Fortunately for consumers, the cross-eyed development tester seen here isn't it. But like momma always said, it's what's inside that counts, and Hefty bag four-doored dose of Zoom-Zoom appears to be no different.

According to Edmunds Inside Line, the mule's camouflage is probably masking the 2008 Mazda 6's chassis. Judging by the shots seen here, the 6 is set to grow, likely in all dimensions. As the 6 has been left behind both in size and power by newer competitors, expect a more capacious interior and a driveline offering something a bit sexier than the 215 horsepower, 3.0-liter V6 currently on offer. Edmunds is betting that the replacement powerplant will be parent company Ford's new 3.5-liter V6 set to serve under the hoods of the Ford Edge, Lincoln MKX and MKZ. In the latter vehicles, the six-pot has been rated around 265 horses and 250 lb.-ft. of torque.
