Take an RS 5 Coupe, add three doors, and what do you get? Quite obviously you get the most incredible performing estate car on the market; a car with enough thrill factor to make even the most prodigious family man smile at the thought of a trip to grandma’s house. Even with 2.5 kids, the family dog, and a weekend’s worth of snacks loaded up, the RS 4 Avant will blow the doors off of most anything it encounters short of a supercar. The rich and silky rasp of this 4.2-liter V8 as it approaches a vivacious 8,500 RPM redline is an audible wonder. This is a wagon that will eat M3s as it barks through each gear of its seven-speed, dual-clutch transmission. Sure, it’s a wagon, but one look at the huge air intakes up front and its sweeping graceful form and distinctive RS 4 badging will attract attention from anyone who appreciates the notion of practicality being outmatched by performance.
