Why does the old Jetta have small displacement but strong power?

[OBrielle]

Here are the specific reasons: 1. Lightweight body: Due to technological limitations, the old Jetta era didn't have many fancy configurations, resulting in lower body weight. Models like Urban Spring, Urban Sunshine, and Avant-Garde had a curb weight of around 1,100 kg, at least 200 kg lighter than most modern compact cars. 2. Transmission differences: The old Jetta mostly used manual transmissions, so acceleration speed largely depended on the driver's skill. Modern cars mostly use automatic transmissions tuned for smooth starts, making the old Jetta appear faster in acceleration. 3. Engine differences: Similar to transmissions, modern car engines are tuned to prioritize smooth starts, naturally limiting initial power output. The old Jetta's cable throttle engine was relatively simpler and more aggressive - it would deliver full power output whenever the accelerator was pressed.
