BMW has revealed the third-generation BMW Z4 roadster at the Pebble Beach Concours d’Elegance in Monterey, Califronia. Based on new underpinnings codenamed G29, the BMW Z4 has been co-developed with Toyota’s upcoming Supra, which is also based on the same platform. Other mechanicals such as the chassis, suspension and electrical components have been taken from BMW’s cluster architecture (CLAR) platform. This is the same platform which is also used in other models from BMW such as 5-Series, 7-Series, X3, X4 and X5.
In a bid to improve the driving dynamics, BMW has equipped extra-wide sill elements in the new-gen Z4 which are claimed to increase the torsional rigidity by 30 per cent over the outgoing model. According to company claims, the new Z4 is the stiffest open-top car by BMW so far. On the aesthetic front, the third-gen model adopts a distinctive design theme which differentiates it from its predecessor. The proportions have been changed as it measures 70mm wider and it now comes with a power-operated fabric hood. With the folding hard top removed, the new Z4 weighs around 60 kg lighter which further helps lower the centre of gravity and aide more sporting driving dynamics.
The front-engine, rear wheel drive layout has been carried out, while the motor has been placed in the engine bay which helps maintain a 50:50 weight equilibrium from front to rear. Insides of the Z4 layers a new driver-centric dashboard, a new digital instrument display, a touchscreen infotainment system, new seat and new set of controls. It additionally comes with a head-up display and a Harman Kardon sound system that are standard on the M40i M Performance First Edition.
Under the hood, the top-spec variant will receive the same 3.0-litre, in-line six-cylinder turbo-petrol unit that powers other models in the BMW’s line-up. In terms of power, the six-cylinder engine makes 340 bhp against 450 Nm torque. This engine is claimed to propel to 100 km/h from rest in just 4.6 seconds while attaining a top speed of 250 km/h. The entry-level Z4s including the sDrive20i and sDrive30i will get a 2.0-litre, four-cylinder turbo petrol engine that will put out 152bhp/250Nm and 264bhp/390Nm respectively. As for the transmission options, it could come with a standard eight-speed automatic gearbox along with an optional six-speed manual unit. It will additionally get an electronically controlled rear differential.
