We're not sure a cheetah is going to confuse its mate with this particular compact crossover, but the CX - 5 does have a sense of
rear weight bias not unlike the Infiniti FX, and the overall effect is attractive if not groundbreaking.
Its 49:51 weight ratio ensures that it remains beautifully balanced through corners, while the slight
rear weight bias maximises straight - line acceleration and traction.
Furthermore, with the batteries integrated beneath the floor, a rear - wheel drive configuration, and a 48:52 front - to -

I can assure you that
your rear weight bias is not the cause of the problem.
Better corner entry: Cars with
a rear weight bias will steer quicker and have a natural tendency to oversteer.
The 911's
rear weight bias helped rotate the car during the sessions where we practiced slaloms and Scandinavian Flicks, its communicative steering relayed clear warnings of understeer, and its engine — whether in the 325 - hp Carrera 4 or the 355 - hp Carrera 4S — made sure that there was always enough power to push through the snow.
Jumping into an older 911, you always feel that
the rear weight bias is out to get you, even if the reality is rather different.
It's low, mean, and proudly shows off its mid-engine configuration and 42/58 percent front - to -

rear weight biased car.
Not exact matches
The little Frenchman's specs are perhaps equally compelling, down to its low

rear -
biased weight distribution.
Mechanical grip is aided by a
rear -
biased weight distribution (54 percent of the F12's
weight is on the

rear, 255 / 35s in front, all on twenty - inch wheels).
What one doesn't notice at relatively low speeds are the E-tron's 70 percent
rear -
biased torque split, its 42/58 percent front /
rear weight distribution, the torque vectoring that combats excessive understeer and oversteer, or the qualities of the suspension, which uses control arms in the front and
rear.
As you might imagine, having such a
rear -
biased weight distribution caused some insane front - end liftoff during launch.
The chassis is balanced such that you can hang the tail out like a hero through corners and roundabouts — that extra

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.)
Does it upset the already

weight bias.
The Bora's four - wheel independent suspension — a first for the Modenese brand — used conventional springs and dampers rather than Citroen's cushy hydropneumatic system, and its
rear -

weight saving per car, reducing unsprung and rotating mass and improving brake cooling.
Manage the
weight, keep the front wheels pinned, and apply the throttle liberally and the
rear -
biased all - wheel drive system defaults to oversteer — however mild — to give a most un-SUV-like experience mid-corner.
Weight aside, it's easily as competent through twisting roads as any competitor is — and all - wheel drive assuredness with a
rear -
bias actually makes it feel exciting in a way a car of this size surely shouldn't.

It's only in full - attack mode on really tight roads or a racetrack that the car's inherent forward
weight bias rears its head, resulting in some occasionally tricky handling behavior at the limit.
Common wisdom tells that a FWD pickup is a bad idea as
weight added to the bay will transfer the
weight to be

weight and grip on the
rear wheel instead of the front wheels where the power is sent.
Engineers have crafted the AMG GT on an aluminium spaceframe with a
weight bias of 53 percent at the

Maserati also has worked hard to get the
weight distribution to be just a bit more sporty
biased with 51 % on the
rear, not quite the 53 % they could get with a
rear transaxle gearbox but remarkable nonetheless considering the gearbox is now mated to the engine directly in the front of the car ever since doing away with their famous transaxle design that housed the controversial DuoSelect transmission.
