The 2013 Volkswagen Passat is offered in three different trims: S, SE and SEL. Among those trims, there are three different powertrains. Base 2.5 S, 2.5 SE and 2.5 SEL models come with a 177-horsepower, 2.5L 5-cylinder engine, offered either with a standard 5-speed manual gearbox or optional 6-speed automatic. TDI SE and TDI SEL Premium models add the 140-hp, 2.0L TDI diesel 4-cylinder engine, while top-of-the-range 3.6 SE and 3.6 SEL models step up to a 280-horsepower, 3.6L 'VR6' 6-cylinder engine. Both the TDI and VR6 engines come only with a 6-speed dual clutch DSG automatic transmission that can pull of remarkably quick shifts. Base Passats move quickly enough with their smooth standard 5-cylinder engine. The VR6 is the performance pick of the lineup; it's especially strong, smooth and responsive. But the TDI has the potential to put smiles on lots of faces; with an EPA highway fuel economy rating of 43 mpg and a meaty 236 pound-feet of peak torque, this engine has more power than one might think and can move up to speed on the highway--or up long grades--without strain. The rack-and-pinion power steering is light while parking but well-weighted on the highway and the Passat has a pretty nimble feel for a mid-size sedan. The new Passat's larger cabin is now truly mid-size, with a spacious, airy feel to the interior, enhanced by an instrument panel that doesn't swoop around but instead helps yield the most space in front of driver and passenger. The backseat is very generously sized--with enough headroom and legroom for most adults--and getting in and out is easy. Across the model line, the Passat comes with a 60/40-split folding rear seatback. The 2.5 S model, which starts at $20,845 and comes better equipped than most base models. A Bluetooth hands-free interface, air conditioning, remote locking, power accessories, a trip computer, steering-wheel controls and a 6-speaker CD sound system are all standard. The SE model adds leatherette upholstery, a power driver's seat, heated front seats, power heated side mirrors, an upgraded sound system with touch screen and 17-inch alloy wheels. 2.5 SEL models bring a much more upscale look and feel with footwell lighting, added chrome trim, sport seats, a backseat ski pass-through and a navigation system. The SEL Premium model gets fog lamps, seat memory settings, push-button start and full leather upholstery. Appointments are similar in TDI models, only the SEL Premium Package includes 18-inch alloys and woodgrain trim. Top 3.6 SE and SEL models also get a sunroof and chrome-tipped dual exhaust system in addition to the SEL Premium equipment. All Passat models include six standard airbags--including side-curtain airbags that cover front and rear occupants--plus standard electronic stability control, anti-lock brakes and hydraulic brake assist.
