Yes, you've seen the BMW Z4 in full production guise already. The German roadster got a full reveal at the 2018 Pebble Beach Concours d'Elegance less than a month ago. But that was specifically the M40i First Edition, which separates itself from lesser Z4s by its Frozen Orange Metallic paint and anthracite fabric top. The models you see here — the 2019 BMW Z4 sDrive30i Roadster and 2020 BMW Z4 M40i Roadster — are the regular-grade versions that'll soon be available at a dealership near you.

Initially, the Z4 will come with a 2.0 liter four-cylinder TwinPower turbocharged engine sending 255 horsepower and 295 pound-feet of torque to the rear wheels through an eight-speed automatic transmission. Tweaks to the engine's fuel injection system and electronic brain allow this latest 2.0-liter to make 15 more hp and 35 more lb-ft than the previous version. BMW claims it'll do 0-60 in 5.2 seconds.

Coming later — note the 2020 model-year designation — will be the M40i and its 3.0-liter turbocharged inline-six-cylinder engine. That model will put out 382 ponies and 369 lb-ft, which is enough gumption to push the Roadster to 60 in 4.4 seconds. BMW says its latest 3.0-liter is smoother than the outgoing unit while also making 47 more horsepower. It too will use an eight-speed automatic transmission.

BMW's upgraded M Sport parts are applied liberally to the M40i. Adaptive suspension with electronically controlled dampers join upgraded brakes and a rear electronically locking differential as standard equipment on the six-cylinder Z4, and are optional on the four-cylinder. Eighteen-inch wheels are standard and 19s are optional across the board, with wider staggered tires on the more powerful model.

Inside, a 12.3-inch digital instrument cluster sits front and center, and BMW's latest seventh-generation iDrive software runs on the centrally mounted 10.25-inch infotainment screen. M Sport models get an optional and exclusive Frozen Gray exterior color and a leather and Alcantara interior package to go along with seats featuring electro-pneumatic adjustable bolstering. In more practical news, the trunk's 9.9 cubic feet is 50 percent larger than the last Z4, and it stays constant whether the top is up or down.

Expect the Z4 30i to hit dealerships in March. We'll have to wait and see when the M40i starts filtering in.

The entry-level 2019 BMW Z4 sDrive30i is $50,595, which is $49,700 plus $995 handling and destination. This is the model will launch first next year, sometime in spring, followed by the M40i. Not only does it keep the little Z-car glued to MSRP earth, it carries over the same price as last base-model Z4 in the U.S., the 2016 sDrive28i, while adding 15 more horsepower.

The sDrive30i uses a 2.0-liter turbo four-cylinder with 255 hp and 255 horsepower 295 lb-ft of torque, posting a 0-60 time of 5.2 seconds with the eight-speed automatic and standard launch control. That compares to the M40i, with a 3.0-liter turbocharged inline-six putting out 382 hp and 369 lb-ft. The sixer does the 60-mph sprint in 4.4 seconds. Back to price comparisons, the Z4 M40i starts at $64,695 before destination, which is $1,665 less than the 2016 sDrive35is RWD that had 335 hp.

The sDrive30i comes standard with LED headlights and the Sport Line trim that adds satin aluminum exterior accents and 18-inch V-spoke orbit gray wheels. Both it and the M40 ride on 18-inch rims with 255-width front tires and 275-width rear tires. Inside, the junior droptop comes with BMW's Live Cockpit Professional Instrument panel, multifunction Sport steering wheel and variable steering, M Sport seats, and dynamic cruise control. A Track Package for the sDrive30i bundles the adaptive dampers, electronically controlled limited-slip differential, and M Sport brakes that come standard on the M40i.

For those keeping tabs on the segment, the 300-hp Porsche 718 Boxster starts at $60,050 out-the-door, about $9,500 more than the Z4 sDrive30i. The Audi TT Roadster goes for $49,395, with 228 hp and 258 lb-ft it's much closer in spec than newness. And the Mercedes-Benz SLC 300 — much older and with an uncertain future — with 241 hp and 273 lb-ft starts at $48,950 before destination, making it $750 less than the Z4.
