The
5
Series is an important model for
BMW,
particularly in North America where it's the brand's second best seller
behind the
3
Series. Heading into 2010, BMW has expanded its mid-size line
with the new Gran Turismo body style already on sale. However, the
volume leader for the 5 Series is the four-door sedan, which officially
debuts today. The 2011 model transitions to a new platform architecture
shared with the latest
7
Series as well as the upcoming Rolls-Royce Ghost. The 5
Series sedan gets a four-inch shorter wheelbase than its siblings, but
at 116.9 inches, it still stretches well past its competition. The new
Mercedes-Benz E-Class runs a mere 113.1 inches between its axles and
the Cadillac CTS is 113.4 inches.
From a technical
perspective, the new 5 Series picks up much of what can be found in the
7 Series and the Gran Turismo.
Since the 5 Series now shares its
platform with the 7 Series and GT, the suspension is essentially
carried over from the other two with multi-link arrangements at all
four corners, dispensing with the struts of the five previous
generations. The outgoing E60 5 Series marked the debut of active front
steering for BMW with a steering ratio that varied based on vehicle
conditions such as speed and lateral acceleration. The new F10 (BMW's
internal nomenclature for the latest 5 Series) adds to that electric
power steering assist, which should help reduce parasitic power loss
and improve efficiency. How it impacts steering feel remains to be
seen, although the 7 Series felt quite good for such a large car when
we tested it earlier this year.
The F10 also picks
up features like optional active rear-wheel steering, which
countersteers the rear wheels for a tighter turning circle while using
in-phase steering at speed for extra stability. Other options include
an adaptive damping system and active roll control to further minimize
lean during cornering.
Inside, the new 5 Series also picks up
themes from the GT and 7 Series with a return to an instrument panel
layout where the center stack is tilted toward the driver for improved
ergonomics. While BMW gave the Gran Turismo an elevated seating
position for that "command view," the 5 Series retains a lower position
more typical of sedans. Barely a year after introducing its third
generation of iDrive in the 3 Series and 7 Series, the new 5 Series
gets what BMW is describing as generation four. It's not clear at this
point how much better it is, but hopefully the system will have
expanded voice controls to get deeper into the menus without having to
use its control knob. All models get an LCD display in the dash to
display audio and climate control information, while cars without the
navigation system get a seven-inch display and those with get the
gorgeous 10.2-inch panel from the 7 Series.
