In the early 1930s, Skoda didn't just build cars; they built **icons of smoothness**. The **Skoda 645** and **633** represented the brand's move into high-performance 6-cylinder engines, bringing a level of refinement that was previously reserved for the ultra-wealthy.
### **1. Skoda 645 (1929–1934): The Aristocrat**
The **645** was a heavy-duty luxury liner. Its name stood for **6 cylinders** and **45 horsepower**.
* **Engine:** 2.5-liter (2,492 cc) inline-6.
* **Performance:** 45 hp with a top speed of **90 km/h**.
* **Design:** Known for its massive chrome grille and spacious interior, it was the preferred choice for diplomats and high-ranking officials who needed a "moving office."
### **2. Skoda 633 (1931–1934): The Compact Powerhouse**
The **633** was a miracle of engineering—it put a 6-cylinder engine into a smaller, more agile body.
* **Engine:** 1.8-liter (1,792 cc) inline-6.
* **Output:** 33 horsepower.
* **The Legend:** Despite its smaller size, it was incredibly tough. In 1932, a Skoda 633 successfully crossed the **Sahara Desert**, covering 1,000 km of sand and rock, proving that Skoda’s 6-cylinder engines were unbreakable.
### **Why They Matter:**
These models shifted Skoda from "reliable transport" to "engineering excellence." They introduced the world to the **vibration-free** experience of a six-cylinder engine, setting a benchmark for comfort that defined the golden era of Czech motoring.
