Before the world premiere in Paris, there are now also the technical data for 2019 BMW Z4 sDrive30i and Z4 sDrive20i Roadster with turbocharged four-cylinder B48.
BMW on Tuesday released the powertrain and performance specifications for the 2019 BMW Z4, nearly a month after unveiling the new two-seater roadster at Pebble Beach.
The base 2019 BMW Z4, dubbed the Z4 sDrive30i Roadster, will be powered by a 2.0-liter turbo-4 developing 255 horsepower and 295 lb-ft of torque. The basic turbo-4 is linked to similar engines from other BMWs, including the 2 and 4 series, but with 7 more horsepower and less weight to move compared to larger coupes and convertibles. According to BMW, the cabriolets on the Z4 base weighed 3,287 pounds, about 400 pounds less than an automatic 2-Series coupe.
With less weight to move and more power, the 2019 BMW Z4 sDrive30i will run up to 60 mph in 5.2 seconds. As a comparison (or boasting), a BMW 230i 2018 performs the act in 5.6 seconds.
Those who want more cylinders and more power can opt for the Z4 M40i, which features a 3.0-liter turbo engine with an in-line 6-cylinder engine with 382 horsepower and 369 lb-ft of torque. Here again, the turbo-6 is borrowed from other M40 brand machines, but has more power in the Z4; the new convertible has 47 hp more than the M240i. This brings up the Z4 M40i to 60 mph in 4.4 seconds, compared to 4.5 seconds for the M240i.
Both engines send power to the Z4\’s rear wheels through an 8-speed automatic transmission with shift paddles. No manual is on the order form.
While the new 2019 BMW Z4 has grown 3.3 inches longer, 2.9 inches longer and 0.5 inches longer than its predecessor, the wheelbase is shorter by an inch. A wider track of 2.45 inches at the front and 3.86 inches at the rear gives the new Z4 a more aggressive and planted position.
The front suspension is a double-hinged strut, borrowed from Series 3, with a five-link rear suspension. BMW has used aluminum for multiple suspension components, from suspension arms to spherical bearings to reduce weight, which should allow more precise handling.
The more powerful M40i model includes an M Sport adaptive suspension, M Sport brakes and an M Sport differential. All are optional on the sDrive30i model.
Offset tires wrap 18-inch wheels, while larger 19-inch wheels are available. The Z4 M40i can carry 275 wide on the rear tires and 255 on the front.
Active safety technology, including frontal collision warning with pedestrian detection and automatic low speed emergency braking, is standard. Adaptive Cruise Control, Blind Spot Monitoring and Rear Cross Traffic Alert are grouped into an optional package.
The 2014 Z4 sDrive30i Roadster will arrive in March 2019, while the 2020 Z4 M40i Roadster will follow in the second quarter of 2019. BMW has not specified how much the car would cost when it goes on sale.
