BMW 4 Series Convertible 2021 Australian price and specs

---

Following the full launch of the 4 Series coupe, BMW Australia has announced pricing for the remarkably attractive drop-top 4.

The medium-premium convertible starts from $89,900 before on-road costs and mirrors the engine line-up of the coupe with 420i, 430i and M440i powertrains. A full price list appears at the end of this article.

Obviously the new ‘G23’ 4 Series convertible mirrors the design language of the coupe, divisive grilles and all. 

With the roof down that long rear deck evokes past Bavarian efforts including the E30 and E36 3 Series convertibles. The added visual length makes the convertible a more successful design than the coupe in our eyes. All with the benefit of being more practical than the Z4.

To keep the 4 Series convertible from feeling like a wet noodle, BMW has added aluminium under-body reinforcement plates, which makes the G23 4 per cent stiffer than the previous F33. 

Buyers will pay for that soft-top privilege, though, the $89,900 starting price represents a whopping $19,000 premium over the $70,900 420i coupe. Specification of the convertible is at least slightly more generous than the fixed-head. 

For that money buyers get a two-litre four-cylinder engine with 135kW/300Nm outputs sent to the rear wheels via an eight-speed ZF automatic which is standard across the range.

Like the coupe, the 420i convertible is fitted with M Sport styling package as well as LED headlights and 19-inch alloy wheels.

Inside there are Vernasca leather-appointed electrically-adjustable seats, a three-zone climate control system, wireless Apple CarPlay and Android Auto, DAB, wireless phone charging and a 12.3-inch digital driver’s display.

A comfort pack can be optioned for $2,600 which adds lumbar support, keyless entry, seat and steering wheel heating and refined air collar. 

For $107,900, the 430i is equipped with the same two-litre turbocharged engine in a higher state of tune, it kicks out 190kW and 400Nm. Adding to the spec of the 420i, the 430i gets adaptive cruise and lane-trace assist, adaptive suspension, M Sport brakes and 360-degree monitor.

Options for the 420i and 430i include a $4,300 visibility package that brings ambient lighting and laser lights.

At the top of the range is the straight-six powered M440i xDrive, which teams a 285kW/500Nm ‘B58’ engine with a rear-biased all-wheel-drive system for $135,900.

Bespoke 19-inch alloy wheels, cerium grey mirror caps and other exterior highlights identify the M440i from the outside. 

Inside, customisable ambient lighting, knurled control dials, lumbar support, laser lights and a harman/kardon soundsystem further bolster the range-topping spec. 

The all-new BMW 4 Series convertible will go on sale in Australia by early 2021 from $89,900.
