I'm talking about the 2006 version that's been out for 6 months...it's the only engine the Wiesmann is available with.
2006 7 Series:
Design enhancements inside and out are complemented by more power for V8 models
Since its introduction in 2002, the fourth generation 7 Series has proven to be the most successful 7 Series ever. The 2006 7 Series exterior receives subtle but significant refinements. Forward of the windshield, new elements include a larger rendition of BMW’s traditional “kidney” grilles; a new bumper/spoiler ensemble; new headlights and foglights; and a re-contoured hood. The rear bumper’s wraparound tucks in more noticeably at the wheelwell and thus visually emphasizes a 14-mm/0.6-in. wider rear track. Both 750 models have a new standard wheel design, with seven relatively wide spokes reaching right out to the rim. The trunklid is newly shaped while retaining the original’s advantages in terms of aerodynamics and cargo space; the taillights now wrap into the lid, and are accented by a slender bright strip.
The refinements are carried into the interior as well. New climate-control knobs present improved tactile feel to the user, and are trimmed in an elegant new Titanium galvanic material that also appears in other details. The iDrive system’s controller has a new, handier shape and a handsome leather insert on top. Functional enhancements include the audio system’s new hard controls for AM/FM and entertainment source selection; MP3 capability added to the CD changer (standard 760i/Li, optional 750i/Li); and a Bluetooth cellphone interface. Whereas previously the 7 Series came standard with an installed (but also portable) phone, owners will now select their own phone from a list of BMW-approved handheld phones and can keep up with the latest developments in this fast-moving technology while also enjoying standard hands-free calling, auto-dial functions and Voice Command convenience. Encompassing an extensive array of features and functions within its pioneering color-display-and-controller concept, iDrive has again been refined and made more user-friendly.
The new 750i and 750iL feature a new 4.8-liter VALVETRONIC V8 engine. With 360 horsepower and 360 lb-ft of torque, this represents an increase of 35 horsepower and 30 lb-ft of torque over their predecessors. Although official 0-60-mph acceleration times are little changed at 5.8 seconds, the real story here is more urge virtually anytime the driver presses down on the accelerator pedal, especially at midrange speeds. The 6.0-liter V12 in the 760i and 760Li remains unchanged offering 438 horsepower and 444 lb-ft of torque. Both are mated to a 6-speed STEPTRONIC automatic transmission.
The price of the 750i and 750Li are $71,195 and $75,195 respectively. This represents a $600 increase over the previous models. Prices for the 2006 760i and 760Li are $110,695 and $118,095 respectively.
