Denza B5 vs Polestar 4
Two electric cars go head to head. Which EV is the better buy for Australian drivers in 2026?
Specifications and pricing correct at time of publishing. Prices are RRP before on-road costs unless stated otherwise. Always confirm with the manufacturer or dealer before purchasing.
Plug-in hybrid fuel economy is shown as a hybrid (battery depleted) so it compares fairly with the other car. A PHEV's official "combined" figure assumes you start every trip fully charged, so real-world economy depends on how often you plug in. Electric range shows how far it goes before the petrol engine is needed.
Price Breakdown
The Denza B5 starts from $74,990 before on-road costs, while the Polestar 4 opens at $78,500. That makes the Denza B5 the more affordable entry point by $3,510.
Once you factor in stamp duty, registration, CTP insurance, and dealer delivery, expect to add roughly 8-12% on top of the RRP depending on your state. That puts estimated driveaway prices in the ballpark of $82,489 and $86,350 respectively.
Both models qualify for Fringe Benefit Tax (FBT) exemption, which is a significant advantage for salary-sacrificed novated leases. Depending on your tax bracket, this can save $5,000-$15,000+ per year compared to an equivalent ICE vehicle.
Safety Rundown
Both the Denza B5 and Polestar 4 hold a 5-star ANCAP safety rating. Adult occupant protection scored 86% for the Denza B5 and 92% for the Polestar 4.
Where the two diverge is in active safety technology. The Polestar 4 packs more ADAS features with 9 out of 10 key systems fitted, compared to 4 in the Denza B5.
Both include the essentials: autonomous emergency braking, lane keep assist, adaptive cruise control. The Polestar 4 adds a 360-degree camera that the Denza B5 misses.
Feature Showdown
The Denza B5 features a 15.6-inch touchscreen paired with a 12.3-inch digital dash, while the Polestar 4 gets a 15.4-inch display and 10.2-inch instruments. Apple CarPlay and Android Auto are standard across both.
The Denza B5 stands out with Apple CarPlay and Devialet audio that you will not find on the Polestar 4. The Polestar 4 counters with wireless Apple CarPlay/Android Auto, wireless charging, panoramic roof, heated front seats, ventilated seats, power tailgate, Bowers & Wilkins audio and ambient lighting. Which feature set matters more depends on your daily routine and priorities.
Interior trim differs: the Denza B5 gets leather upholstery while the Polestar 4 offers synthetic leather.
Drivetrain
The Denza B5 uses a Petrol Turbo PHEV producing 400kW and 760Nm of torque, sent through a 1-speed auto to a AWD layout. It covers the 0-100km/h sprint in 4.8 seconds.
The Polestar 4 responds with a Electric Motor making 200kW and 343Nm, paired to a single-speed fixed gear driving the rear wheels. It gets to 100km/h in 7.1 seconds.
The Denza B5 has the clear power advantage at 400kW vs 200kW. In the real-world sprint, the Denza B5 is 2.3s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Space & Comfort
The Denza B5 measures 4,888mm long on a 2,800mm wheelbase, 48mm longer than the Polestar 4 at 4,840mm (2,999mm wheelbase). The longer wheelbase on the Polestar 4 generally means more rear legroom.

For towing, the Denza B5 leads with a 3,000kg braked capacity vs 1,500kg. That 1,500kg difference matters if you regularly hitch up.
