The twin-under-the-skin to Toyota's Supra will start just under $85,000.

BMW has announced pricing and specifications for its twin-under-the-skin to the Toyota Supra, the Z4, ahead of its April arrival in local showrooms.

The three-pronged Z4 range will start with the sDrive20i, priced from $84,900 before on-road costs. Power comes from a 2.0-litre four-cylinder turbocharged petrol engine making 145kW and 320Nm, mated exclusively to an eight-speed ZF automatic transmission.

Claimed fuel economy is 6.5L/100km on the combined cycle, while the 100km/h sprint takes a claimed 6.6 seconds.

Although it's the base model, the 20i isn't what you'd call a stripper. It rides on 18-inch alloy wheels as standard, and the car is fitted with the M Sport Package which brings a 10mm lower ride.

As with all Z4 models, it's fitted with a cloth top capable of folding in just 10 seconds at speeds up to 50km/h.

With that said, you're not able to option the 20i with the electric M Sport Differential that's optional on the 30i and standard on the M40i. Adaptive M Suspension is optional on the base model, but standard on its bigger brothers.

Jumping to the sDrive 30i maintains the same engine, but bumps outputs to 190kW and 400Nm. The price also rises to $104,900 before on-roads, while the 100km/h sprint time drops to 5.4 seconds.

Along with the equipment listed above, the 30i rides on 19-inch alloy wheels as standard, gets M Sport brakes, and gains niceties like keyless entry and, adaptive cruise control with stop and go, and adaptive LED headlights.

Jumping to the range-topping Z4 M40i brings a turbocharged inline-six engine pumping out 250kW and 500Nm. It's put to the rear wheels through the same eight-speed automatic as the wider range, but the 100km/h sprint time drops to 4.5 seconds.

Standard equipment includes a unique suspension setup, an M Sport Differential, and a 12-speaker harman/kardon surround sound system.

Pricing starts at $124,900 before on-roads.
