Porsche is 
doubling its range of driving fun in the new 911 generation by launching
 the all-wheel drive Porsche 911 Carrera 4 on the market in four model 
versions. The new sports cars with their uniquely powerful proportions 
combine the excellent traction and driving stability of the active 
Porsche Traction Management (PTM) system with the benefits of 
lightweight design, new engines and additional assistance systems - 
traction and dynamics to the fourth power.  Despite enhanced engine and 
driving performance, all four models consume significantly less fuel 
than their respective previous models; in some cases the savings add up 
to as much as 16 per cent. So, the new all-wheel drive 911 is 
consistently following the same course as the 911 Carrera Type 991 
presented in 2011. The Carrera 4 takes top efficiency and performance to
 an even higher level.  The most distinctive identifying feature of the 
911 with all-wheel drive is still the wide rear section: compared to the
 two-wheel drive 911 Carrera models, the wheel housings at the rear are 
each 22 mm wider, and each of the rear tyres is 10 mm wider. This 
increases the track width of the 911 Carrera 4 by 42 mm, and the track 
width of the S-model by 36 mm. The impressive look at the rear is 
highlighted by an exclusive tail-light panel with parking light and rear
 light functions. The tail-light panel runs directly under the spoiler 
edge and visually joins the two rear lights. For one, this emphasises 
the powerful back end of the vehicle; for another, it lends the 
all-wheel drive models a unique and very distinctive night design. When 
the lights are turned on, the illuminated rear light band visually 
connects the rear lights and signals that a new all-wheel drive 911 is 
driving ahead.
