Lexus GS 350 vs Audi A6 03/30/2011
Purchasing a luxury sedan is a considerable investment, which means that drivers will really have to compare all their options before dropping $50,000. To make the process a bit easier, we compared to of the more popular models, the Audi A6 and Lexus GS 350, to see which was the better value.

The A6 retails for $45,200, while the GS 350 is just a bit more expensive at $46,100. The Lexus has the better warranty, with 6 years/70,000 miles compared to Audi's 4 year/50,000 mile pledge.

Under the hood, drivers can either go for fuel efficiency on the Audi or pure power on the Lexus. The A6 is rated at 21/30 mpgs, while the GS 350 gets 19/26. However, the Lexus produces 303 horsepower and 274 lb-ft of torque, compared to just 265 hp and 243 lb-ft on the Audi.

Both interiors are suitably luxurious, and while neither vehicle holds a clear edge over the other, there are some differences. The Audi gets a built-in hard drive and HD radio standard, while Lexus drivers will enjoy heated seats and keyless ignition.

It's ultimately a tough call between these two cars, but we give the nod to the Lexus thanks to its superior power and warranty.
