Cómo imprimir la clase de JavaScript en la tabla

Tengo una clase llamada 'Coche'. Lo que quiero es que cuando el usuario seleccione 'Maruti' de la opción de selección, todos los datos del automóvil rápido se impriman en la tabla. Cuando elijo Maruti, no imprime nada y tampoco hay un error de consola.

 <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> </head> <body> <select id="sel" onchange="selected();"> <option>---choose--</option> <option>Maruti</option> <option>Tata</option> </select> <table></table> <script> let Car= class { constructor(name,power,torque,weight){ this.name=name; this.power=power; this.torque=torque; this.weight=weight; } } class Maruti extends Car{ constructor(name,power,torque,weight){ super(name,power,torque,weight); } } class Tata extends Car{ constructor(name,power,torque,weight){ super(name,power,torque,weight); } } var swift = new Maruti('swift',103,100,870); var safari = new Tata('safari',105,138,1070); function selected(){ var sel = document.getElementById('sel').value; for(const key in Car){ if(sel[1]=='Maruti'){ document.querySelector('table').innerHTML+= '<tr>' + '<td>' + key +'</td>'+ '<td>'+ swift[key]+'</td>' + '</tr>'; }else{ document.querySelector('table').innerHTML+= '<tr>' + '<td>' + key +'</td>'+ '<td>'+ safari[key]+'</td>' + '</tr>'; } } } </script> </body> </html>
