Gearheads almost universally consider rear-wheel-drive as the best setup to get the best handling car. I consider wagons to be the best compromise for family vehicles that do no have to seat more than five people on a regular basis. This is a site devoted to forced induction so that brings us to a crossroads where two sportwagons are waiting for us now that we are in the 2012 model year. The Cadillac CTS-V Wagon which debuted in 2011 and the brand-new Mercedes-Benz E63 AMG Wagon.
Cadillac starts with a C so I will be looking at it first.

With its supercharged V8 the Cadillac is bolder brasher and significantly cheaper than the Mercedes
The CTS-V is a package that boggles my mind. General Motors, the company that will sell you the same old-school ,body-on-frame SUV with one of three manufacturer badges has made a rear-wheel-drive station wagon that is powered by a 6.2L supercharged V8?! Oh and to add to the delightful surprises it comes standard, with a six-speed manual gearbox. I also have to mention the optional Recaro seats that are a $3,910 option but only a fool would buy one of these without Recaros.
Another must-have is the $1,660 panoramic moon-rof. You cannot get this on the sedan, and the giant skylight is reason enough for me to get the wagon. The automatic gearbox uses six-speeds, has paddles and stickers for just under $ two grand. But do you really want the automatic with this car? Yes it is a GM so the automatic is generally pretty close to on par with the manual but remember this is a detuned version of the supercharged V8 from the Corvette ZR1. Don’t you want to enjoy working a stick shift that is moving 556 horsepower and 551 lbs/feet of torque to 100 4.5 seconds?!!

The Mercedes is more subtle, more comfortable, more refined and more expensive
The Cadillac carries an MSRP of just under $80,000 once you add some must-have options. You could save about $10,000 by buying one in the United States but then you have to deal with warranty headaches and import duties.
The Mercedes is entering its first year of production with the new twin-turbo 5.5 litre V8 that replaces a naturally-aspirated 6.2 litre unit. The name carries over but the name of the old wagon never made a ton of sense anyway because it should have been the E62. Either way, while the CTS-V is the first fast wagon from Cadillac, the E63 AMG follows a tradition going back to the 1980s.
Because Mercedes has so much experience with fast wagons, they made sure the E63 AMG had two folding seats in the trunk so it will seat seven comfortably and legally. While this is not ideal for seating that many people on a daily basis it works well for the occasional shorter drive.
The Mercedes does however have some major flaws in the form of price. Without any options this car stickers for over $102,000 in Canada and is not much cheaper in the US at $91,000. This is before you get into options, many of which I think are necessary. The first is the AMG performance package, which really should be standard. It costs $7,500 and the first thing it does it boost power. Without this package, the AMG produces 518hp and 516lbs/feet torque. This is not a lot when you consider the vastly cheaper Cadillac. So Mercedes has raised the power to 550 HP and 590lbs/feet torque. Slightly less horsepower than the Cadillac but a lot more torque. It also raises the top speed from 250 to 300 km/h. Lastly is a limited-slip-differential, something that is standard on the Cadillac and should be on the Mercedes.
For $2,500 you can have night vision on the Mercedes which detects pedestrians. This system has been around a while and I think it is worth it if you are spending this kind of money.
Lastly is an option that is divisive. For $13,750 carbon ceramic brakes are an option. These are rotors that never wear out, they never fade and they stop in a much shorter distance than the standard units. on the downside they cost quite a bit, tend to squeal unless you are working them very hard oh and have very little feel so it is difficult to stop gently. The Mercedes is also only available with a seven-speed automated manual. There is no torque converter and there is one computer-controlled clutch. So no clutch pedal but your shifts won’t be as smooth as in a traditional automatic or even a dual-clutch unit from a VW GTI.
The Mercedes does at least come standard with a giant moon-roof like on the Cadillac but even without the carbon brakes this car stickers for $109,000. The Mercedes, with its seven seats, and automatic gearbox seems like the more family-oriented car, rather than the manual-gearbox, five-seat Cadillac. So if you are looking to drive your sleeping kids home in a quick but smooth manner, skip the noisy, jerky, carbon brakes. If you want the faster car, get the Cadillac.
