BMW introduced their new 7-Series model designated the E65 (short wheelbase) and E66 (long wheelbase) in 2002 to much controversy. The first striking difference was the styling - designed by Adrian van Hooydonk and Chris Bangle, this was radically different to the previous organically developing style of previous 7-Series models. The new design was, well, lumpy! The headlights were scalloped below with prominent eyebrows above which housed the indicators, and the lines were multiple curves with a straight lateral that ran right from the front wings to the rear quarter intersecting the rear light clusters.But the part that caused the greatest angst was the boot (ireverantly called the Bangle Butt), which was designed with a hump at the rear much like a spolier which curved up towards the centre - it was huge and it was pretty ugly, a solid vertical slab of steel which failed to follow the curve of the rear quarters. Although it was toned-down during the rapid facelift process it still didn't look right.The second big change was the introduction of BMW's I-Drive system, which centred around a single multi-axis controller to operate the E65's vast electronic systems. Gone were the E38's rows of buttons and dials showing the level of options on a particular car to be replaced by a confusing controller. Rather than a simple poke of the heater button if you were feeling a bit chilly, now you had to navigate through screens of menu's to find the heater settings - it wasn't universally appreciated to put it mildly. Having the I-Drive system removed most of the user-controls, which left the dash open to alternative uses - which seemed to be additional cup-holders.The E65/E66 saw the introduction of a new range of engines, from the straight-6 M57TUD30 turbo-diesel with an inadequate 214 BHP, to the massive V12 N73B60 6- Litre petrol engine, possibly the last of the big V12's with a massive 431 BHP and Valvetronic control over the valve timing.The 2002 - 2003 models suffered from software problems with the I-Drive system producing a substantial number of re-calls with BMW re-purchasing a proportion of E65's in the USA. By 2004 the I-Drive problems were rectified in the main and BMW enjoyed excellent sales of this most popular 7-Series.
