2012 Porsche Panamera Turbo S compare

With a powerful yet efficient engine and high-tech suspension, the pricey 2012 Porsche Panamera Turbo S delivers near-supercar performance, but the cabin electronics fall short of cutting-edge.

The 2012 Tesla Model S sets a new standard for cars of the 21st century by integrating cabin tech equal to anything from the consumer electronics industry and incorporating a long-range, powerful, and efficient electric drivetrain.

The 2013 Audi S7 features a phenomenal amount of tech both in the cabin and under the hood. An impressive sport driver, its fuel economy remains decent enough for a daily commute.

The 2013 BMW 750Li does double-duty as a freeway cruiser and a getaway car, whether you drive it yourself or hire a chauffeur. A wide array of connected features add new capabilities to the already first-rate navigation and stereo systems.

The 2013 Lexus LS 460 F-Sport's performance upgrades don't transform it into a sports car, but add a sporty edge to the luxury sedan's already good cabin and comfort tech offerings.
