In top trim the E500 also improves in performance. Up 15% in torque over the outgoing E430 the car should accelerate with increased energy, especially considering its up only 45.4 kg (100 lb) in curb weight and then factoring in that the 339 lb-ft of maximum torque available begins at a mere 2,700 rpm and extends all the way to 4,200 - a 1,500 rpm power band. Also, its additional 27 horsepower - 302 compared to the E430s 275 - can't be overlooked when winding up the 4,966 cc V8. The E500 incorporates a Touch Shift 5-speed adaptive automatic transmission, allowing quick shifting via steering wheel or gear lever actuation. A more economical E320 is also available, with a more moderate 221-hp and 232 lb-ft of torque, also at a much more accessible price, $69,950 compared to $81,500.
With price in mind, although the base E has only increased in price by $1,600 from the outgoing model, the E500 is a whopping $5,350 more than last year's E430 $76,150 starting price. Why the big increase? Additional accessory content has definitely added to the bottom line.
Mercedes' Airmatic DC, a system that replaces traditional coil springs with air bellows in the struts, is now standard. The system maintains a full inhalation of air during normal driving for increased ride comfort, and then releases air to produce a firmer setting during aggressive maneuvers. When the full sport position is dialed in the system is set to its firmest level while ride height is lowered by slightly more than one half inch. Reportedly, Airmatic DC benefits the E500 with improved stability and crisper turn in when compared to earlier versions.
Another feature that drives up the E500's price over the previous model is a new electronic braking system. While it is said to shorten stopping distances some whom have driven it complain of an artificial feel and pedal modulation difficulties at low speeds.
