Audi RS6 Avant (2008-10, 2013-present)

If you are from the U.S. or Canada, you have probably never seen an Audi RS6 Avant before, unless you've traveled to Europe and claimed to have spotted one. This is because Audi has given up on selling wagons in the North American market, with the exception being the A4 Allroad. The RS6 Avant has been around for three generations so far, beginning in 2002. Displayed above are the previous and current generations of the RS6, which were spotted in London and near the Vatican, respectively.

The previous-gen Audi RS6 (first two pics, in gray) was available from 2008 to 2010. It is powered by a 5.0-liter V10 from the first-gen Lamborghini Gallardo producing 571 horsepower and 479 lb-ft of torque.The sprint from 0 to 62 mph occurs in 4.6 seconds, onto a top speed electronically limited to 155 mph (170 mph delimited). Power is distributed through Audi's signature Quattro All-Wheel Drive via a six-speed tiptronic automatic. This generation of Audi RS6 also utilizes the brand's Dynamic Ride Control Sports suspension system and Multi Media Interface (MMI).

The current-gen RS6 (last three pics, in black and blue) was introduced for the 2013 model year and is my favorite of all three RS6 generations. It ditches the naturally aspirated 5-liter V8 in its predecessor for a 4-liter twin-turbo V8 with 605 horsepower and 553 lb-ft of torque. The launch from 0 to 62 mph takes place in 3.7 seconds, onto a top speed of up to 190 mph when delimited. Like its predecessor, the current RS6 model has Quattro AWD; however, the latter has a new 8-speed tiptronic automatic. Other notable features include start-stop technology and cylinder deactivation, which are both used to increase fuel efficiency.

The closest alternative to the Audi RS6 Avant that Americans can purchase is the RS7, displayed below. The RS7 has the same engine, transmission, Quattro AWD system, and performance figures as the RS6. The main differences between the two are cargo space, kerb weight, and overall dimensions.
Can't go wrong with either RS6 Avant or RS7; personally, I'd be satisfied with either model. Back to the RS6 Avant, this super wagon is an amazing all-around vehicle. It is one of the best at dominating the track, hauling the family on long road trips, getting groceries, and other daily duties. If anyone at Audi is reading this post, a US-spec RS6 Avant would be greatly appreciated, especially by me and countless enthusiasts in this part of the globe.
