BMW has again underlined its powertrain prowess with the debut of a new TwinPower Turbo four-cylinder petrol engine in the BMW Z4 range.

Available in two outputs, 180 kW and 135 kW, the powerplant reflects a new era in BMW engine development utilising advanced turbo-charging technology to maximise both power and fuel economy.

Codenamed N20, it features a twin-scroll turbocharger with VALVETRONIC, Double-VANOS and High Precision Injection.

Spearheading the new four-cylinder turbo range is the 180 kW TwinPower Turbo Z4 sDrive28i. (copyright image)

It sprints from zero to 100 km/h in 5.7 seconds (0.1 seconds quicker than the naturally aspirated predecessor Z4 sDrive30i) thanks to a 13 per cent increase in torque (from 310 to 350 Nm).

Fuel consumption reduces by 21 per cent, improving from 8.5 litres per 100 km to 6.7 litres.

This not only provides a direct customer benefit, but also positions the new Z4 sDrive28i easily below the federal government’s fuel efficient luxury car tax threshold.

As a consequence, BMW has been able to significantly improve the customer value offered by the Z4 sDrive28i with a price of $89,400*, compared to $98,700* for the predecessor Z4 sDrive30i.

The switch from six to turbocharged 4-cylinder engine has endowed the Z4 sDrive28i with the combination of remarkable performance and price below $90,000*.

For the new Z4 sDrive20i, a turbo-charged four-cylinder engine replaces the previous naturally-aspirated six-cylinder engine in the Z4 sDrive23i.

Delivering 135 kW and 270 Nm, the new engine reduces fuel consumption by 1.8 litres to 6.7 litres per 100 kilometres.

The Z4 sDrive20i also slips in below the fuel efficient luxury car tax threshold and is priced from $76,900*, compared to $86,200* for the outgoing Z4 sDrive23i.

This represents a new entry price point for the BMW Z4 Roadster in Australia.

In order to harmonise prices across the range, BMW has also announced new retail prices for the Z4 sDrive35i ($107,500*) and flagship Z4 sDrive35is ($120,500*).

In addition to the standard 6-speed manual transmission, the Z4 sDrive20i and Z4 sDrive28i will also be available with the new 8-speed automatic transmission.

Offering fast, smooth gear changes and excellent fuel efficiency, the new transmission also includes unidirectional gearshift paddles (utilising M shift logic).

The new BMW Z4 sDrive20i and Z4 sDrive28i will be available in Australian showrooms in November this year, whilst revised prices for the Z4 sDrive35i and Z4 sDrive35is are effective immediately.

Manufacturer’s List Prices*:

Z4 sDrive20i: $76,900*
Z4 sDrive28i: $89,400*
Z4 sDrive35i: $107,500*
Z4 sDrive35is: $120,500*
