An Aurion Web site has a little movie to compare the acceleration of the four Aussie sixes. In the line-up:

• Holden Commodore Omega (180 kW 3.6-litre V6)
• Ford Falcon XT (4.0-litre in-line six-cylinder, 190 kW)
• Mitsubishi 380 ES (3.8-litre V6, 175 kW)
• Toyota Aurion AT-X (3.5-litre V6, 200 kw)

The result is astonishing. In addition, Toyota claims the engine uses less fuel than the others. Note the engine size is actually smaller.
