Have you ever noticed how an electric car settles into a corner? The body stays flat. There's no dramatic lean, no unsettling wallow. On a winding road, it feels planted — like the car is holding the tarmac rather than balancing on it.
That feeling has a name in physics: a low centre of gravity. And it's one of the biggest reasons electric cars feel the way they do — not heavier, not floatier, but genuinely composed.
Here's how it works, what it does on the road — and why it matters to anyone driving electric cars in Australia.
1. The physics in one paragraph
Every object has a centre of gravity: the single point where its mass is, on average, concentrated. Picture a tall drinks cabinet on wheels versus a low, wide toolbox on the same castors. Push both sideways, and the cabinet teeters; the toolbox resists. The lower the mass sits, the harder it is to tip.
A car is the same object on a larger scale. When you corner, the car's mass wants to keep going straight while the tyres turn — that's what causes body roll. The higher the mass sits, the more leverage it has to lean. The lower it sits, the less body roll, and the more confidently the tyres can do their job.
2. Why does an EV naturally sit low
This is where electric car design has a structural advantage that's not a tuning trick — it's geometry.
In a petrol car, the heaviest components are scattered — the engine high under the bonnet, the fuel tank in the rear, a drivetrain between them. Engineers work hard to lower that mass, but they're fighting the layout.
An EV is different. Its single heaviest component — the battery — is a flat slab mounted in the floor, at the very bottom of the car. That's hundreds of kilograms of mass sitting as low as physics allows. The electric motors are small and low-mounted. There's no engine up high, no driveshaft through the middle.
The result is a car whose centre of gravity sits close to the ground, with a weight distribution that often approaches the ideal 50:50 between the front and rear axles. That balance is why an EV can feel neutral and settled in corners — the mass is both low and evenly placed.
3. What a low centre of gravity does on the road
Less body roll in corners. The car leans less when you turn, so the suspension can spend its travel on grip rather than fighting gravity.
Better stability in emergency manoeuvres. A low mass is harder to unsettle — swerve-and-recover manoeuvres feel more controlled, with less risk of the body tipping onto its outside wheels.
Calmer under braking and acceleration. With the mass low and centred, the nose doesn't dive as dramatically under hard braking, and the body doesn't squat as much under acceleration. Pitch and roll are both reduced.
More confidence on uneven roads. The body stays composed over ruts and camber changes, so the tyres stay in better contact with the road.
None of this makes an EV invincible — physics still applies. But it means the car starts from a genuinely stable foundation.
4. The honest limits: weight is still weight
Let's be balanced about it. A low centre of gravity is a real advantage, but it's not the whole story.
Electric cars are heavy — the battery adds significant mass. In an emergency stop, that mass still needs to be managed by the brakes and tyres. In a hard corner, the tyres still carry the car's inertia. And if the suspension is poorly tuned, even a low centre of gravity can't fix a floaty, imprecise ride.
That's why the best electric car models treat the chassis as a system: low mass placement is the foundation, but suspension design, damping and tyre choice determine what the driver actually feels. The physics provides the opportunity; the engineering delivers the result.
5. XPENG: working with the physics, not against it
This is where XPENG's engineering approach comes in — combining the low, balanced mass of an EV with suspension and software designed to make the most of it.
The NEW G6 electric SUV and the X9 pair dual-chamber air suspension with an AI-driven chassis. The dual-chamber design lets the system adjust stiffness across a wide range — firmer when you're cornering, more compliant when you're cruising. The AI-driven chassis reads the road in real time and adjusts damping continuously, keeping the body composed over changing surfaces.
Put together: the low centre of gravity provides the stable foundation, the air suspension manages the ride, and modern electric car technology fine-tunes the balance hundreds of times per second. Structure, suspension and software work as one system — which is exactly what "feels stable" means in practice.
Conclusion
It's why an electric car settles into a corner where a tall, top-heavy SUV might lean — and why emergency manoeuvres feel more composed than the spec sheet suggests.
But the feeling isn't automatic — it's engineered. Low mass placement gets the car halfway there; suspension design, damping and intelligent software take it the rest of the way. When all three work together, you get a car that feels planted — not because of marketing, but because of how it's built.
