The Vindicator (also known as Frankenstein '88 and known in Brazil as Roboman) is a 1986 Canadian science fiction film directed by Jean-Claude Lord. It has a protagonist in a blackened space-suit, a pregnant wife, an attempt to communicate, a crushed car, and a scene at the end with the suit being in a museum. All text below is from the Wikipedia summary with my highlighting.
Carl Lehman (David McIlwraith) is a scientist working on a next-generation space suit for the ARC corporation, run by the sinister Alex Whyte (Richard Cox), where all kinds of high-tech research is being conducted. One of these projects is developing "rage program" software that can sense when a user is provoked and take over its brain to destroy the attacker. After Carl confronts Whyte about some suspicious funding cuts, Whyte sends his employee Massey to kill him and disguise the death as a lab accident.
ARC informs Carl's pregnant wife Lauren (Teri Austin) and daughter Catherine (Catherine Disher) that Carl has died. In reality, Whyte is keeping Carl's charred body in a suspension of oxygenating fluid which keeps his brain functioning. Using Carl's space suit and ARC's cutting-edge prosthetics technology, they build Carl a cyborg body and dub him "Project Frankenstein".

Carl stows away on a garbage truck, which drops him into an incinerator. Thanks to his immense strength, he is able to break out and heads for his residence. On the way, some street thugs chase him into an alley, and he kills them in rage. Realizing that the rage program forbids close contact with people, he talks to his wife from outside their house through a synthesizer in their living room.
....
Burt goes to the Lehman residence, where he confesses his lust for Lauren. Rebuffed, he subdues her by strangulation. Hunter later arrives and kills Catherine. Carl shows up in time to crush Burt inside his car, but Lauren gets captured and taken to ARC to lure Carl. Meanwhile, Whyte's girlfriend is being interrogated by the police, hinting that Project Frankenstein will be investigated and defused.
....
Years later, Lauren is visiting a museum with her son Carl Jr. They admire a display of Carl's space suit, which has been successfully deployed on Mars.
