The design was approved in Summer of 2004 and frozen in December 2004. The company announced in 2005 that the two-door coupé would be available for production including the return of the M Coupé. The production car was introduced at the New York Auto Show in April 2006 and was available for sale in late May 2006.{{Cite web|url=https://www.carsguide.com.au/car-reviews/bmw-z4-coupe-evolved-to-a-revolution-9303|title = BMW Z4 2006 review}}

Thanks to its hatch design, the Z4 Coupé offers {{convert|10.1|cuft|m3|abbr=on}} of trunk space,{{cite web|url=http://www.jbcarpages.com/bmw/z4/2008/specs2/|title=2008 BMW Z4 & M Coupe Specs|publisher=JB car pages|access-date=2008-12-22}} compared with {{convert|8.5|cuft|m3|abbr=on}} for the roadster.{{cite web|url=http://www.jbcarpages.com/bmw/z4/2008/specs/|title=2008 BMW Z4 & M Roadster Specs|publisher=JB car pages}}

The Coupe's fixed roof increases torsional rigidity, resulting in a stiffness of {{convert|32000|Nm|lbft|abbr=on}} per degree of body twist on the coupe (compared to {{convert|14500|Nm|lbft|abbr=on}} per degree on the roadster), which improves turn-in and overall handling response.{{cite web|url=http://www.pistonheads.com/doc.asp?c=100&i=15562/|title=BMW Z4 & M Coupé|publisher=Pistonheads pages|access-date=2011-07-27}} The roof has a "double-bubble" contour which serves as an aerodynamic aid and offers more headroom than the roadster with the soft top closed. The Coupé has a sleek fastback rear window that slopes down to an integrated spoiler which is shaped to deliver downforce to the rear axle at high-speed.

The model range for the Coupé was more limited than the roadster, and consisted of the six-cylinder 3.0si and Z4 M model only.{{cite web|url=http://www.caranddriver.com/reviews/2006-bmw-z4-30si-coupe-short-take-road-test|title=2006 BMW Z4 3.0si Coupe|author=AARON ROBINSON|work=caranddriver.com|date=September 2006}}{{cite web|title=Z4 E86 model selection|url=http://www.realoem.com/bmw/en/select?product=P&archive=0&series=E86|website=www.realoem.com|access-date=9 July 2017}} Transmission choices were a 6-speed manual and a 6-speed automatic with shift paddles mounted on the steering column.

Compared with its Z3 predecessor, the Z4 is larger and has a stiffer chassis.{{cite web|title=2003 BMW Z4 first drive|url=http://www.roadandtrack.com/new-cars/first-drives/reviews/a9537/2003-bmw-z4/|website=www.roadandtrack.com|date=6 November 2012|access-date=7 July 2017}} As per the Z3, the front suspension is a Macpherson strut design. The rear suspension uses a multi-link design, instead of the semi-trailing design used by the Z3. {{cite web|title=BMW Z4 3.0i - Long term tests |url=http://www.evo.co.uk/carreviews/evolongtermtests/46372/bmw_z4_30i.html |website=www.evo.co.uk |url-status = dead|archive-url=https://web.archive.org/web/20130708140407/http://www.evo.co.uk/carreviews/evolongtermtests/46372/bmw_z4_30i.html |archive-date=8 July 2013 }}

The Z4 used lightweight materials to offset the increased weight over the smaller Z3, such as an aluminum hood and suspension components, magnesium roof frame. Run-flat tires removed the need for a spare tire, which reduces weight and allows for a larger trunk.{{cite news|title=2003 BMW Z4 - Road test & review|url=http://www.automobilemag.com/news/bmw-z4-2/|newspaper=Automobile Magazine|date=25 November 2002}}

The 6-cylinder engines included all-alloy construction, variable valve timing (double-VANOS), and throttle by wire. Safety technology included four-wheel disc brakes and electronic stability control, incorporating ABS and traction control.

An optional "Sport Package" included added stiffer and lower suspension, 18 inch wheels, and sport tuned electronic steering, throttle and shift parameters ("Dynamic Driving Control").{{cite web|title=2003 BMW Z4 3.0i - Long-Term Road Test|url=http://www.caranddriver.com/reviews/2003-bmw-z4-30i-long-term-road-test|website=www.caranddriver.com|date=March 2005|access-date=10 July 2017}}

The torque was available from 2,500 rpm.

The Z4 M uses hydraulic power steering, unlike the electric power steering used by the rest of the Z4 range. The Roadster used the E46 M3 steering rack, the Coupé the faster M3 CS/CSL rack. Other changes include a wider front track, revised front suspension, wider non-runflat-tires (measuring 225/45 at the front, 255/40 at the rear), and steering geometry. The brakes and the entire rear axle was too from the M3 CS/CSL.
