Mechanical grip is aided by a rear -
biased weight distribution (54 percent of the F12's weight is
on the rear
axle), a five - link rear suspension (the 599 used control arms), and enormous Michelin Pilot Super Sport tires (315 / 35s at the rear, 255 / 35s in front, all
on twenty - inch wheels).
Of course, mechanical grip is aided by a rear -
biased weight distribution (54 % of the F12's weight is
on the rear
axle), a five - link rear
axle (the 599 used wishbones) and enormous Michelin Pilot Supersport tires (315 / 35s at the rear, 255 / 35s at front, all
on twenty - inch wheels.)
Having the engine
on the same side as the driven
axle can increase gas efficiency and help increase grip to those wheels under «normal» circumstances but it also
biases a lot of weight onto one side of the car.
But here's what you can't have
on the Audi: a choice of two biturbo dry - sump lubricated engines; Porsche Active Suspension Management (standard
on the Turbo) and an optional, height - adjustable air suspension; a rear -
biased all - wheel - drive system that can quickly divert up to 100 percent of torque to either
axle via a multiplate electronic clutch; and available ceramic composite brakes and Porsche Torque Vectoring, the latter distributing rear twist from side to side.
However, unlike the differentials
on the drive
axles which are configured to provide torque equally to both wheels, the centre differential is usually set to have a
bias to one set of drive wheels or the other, depending
on application of the car.
Thanks to front mid-engine and transmission in transaxle configuration
on the rear
axle, the AMG GT R has a rear -
biased weight distribution of 47.3 to 52.7 and a low center of gravity.
The RS 4 Avant will run essentially the same powertrain as the RS 5 Coupe, which means a rear -
biased all - wheel drive system, complete with the option of a more responsive Sports differential
on the rear
axle.
Weight distribution is
biased 40 % at the front / 60 % at the rear, reducing inertia
on the front
axle.
The standard - fit AMG Performance 4MATIC all - wheel drive system features a rear -
biased torque distribution of 31 percent to the front
axle and 69 percent to the rear
axle, providing better vehicle dynamics and higher lateral acceleration
on the road, but also improved traction.
- Suspension: front, independent with unequal length A-arms, coil springs, shock absorbers and stabilizer bar; rear, rigid
axle on semi-elliptical leaf springs with
bias mounted shock absorbers - Brakes: power disc / drum - Steering: power assisted, recirculating ball - Weight: 2,570 to 2,680 pounds - Length: 177.2 inches - EPA rating: 19 mpg city / 24 highway - Fuel tank capacity: 13.7 gallons - Base price: $ 7,689
This results in a slightly rear - end
biased axle load distribution of 57 %
on the rear
axle and 43 %
on the front
axle, combined with an extremely low center of gravity at approximately the height of the wheel hubs, which is ideal for driving dynamics.
Both models retain all - wheel drive, with a 69 - percent
bias towards the rear
axle, and they ride
on steel springs supported by active dampers, controlling the four - link front and five - link rear suspension systems.
- Engine: fuel - injected, 116 - horsepower four cylinder - Transmission: five - speed manual or four - speed automatic with overdrive - Suspension: front, independent with unequal length A-arms, coil springs, shock absorbers and stabilizer bar; rear, rigid
axle on semi-elliptical leaf springs with
bias mounted shock absorbers - Brakes: power disc / drum - Steering: power assisted, recirculating ball - Weight: 2,570 to 2,680 pounds - Length: 177.2 inches - EPA rating:...
Torque distribution
on the front and rear
axles, which until now was strongly rear -
biased, is fully variable for the first time.
