OK rivet counters: Audi didn’t invent the double clutch. Citroen offered something similar over 70 years ago, and Porsche’s formidable 962 racer also gave it a go. But Audi has just about perfected the DSG. (The only drawbacks are a certain sluggishness when gently tipping-in and a slight hesitation when paddling down more than one gear, as the DSG shuffles through the intervening ratios.) Even with its quirks, the DSG rules– to the point where the clutch pedal and traditional manual gearbox is a mechanical redundancy, a dead device shifting. In fact, any car manufacturer who doesn’t have a DSG or something similar installed in their performance-oriented products will soon be at a tremendous disadvantage.
