- Fuel System: Multiport Fuel Injection
- Horsepower (approximate): Typically ranged from 268 to 302 hp, depending on the specific tuning and model year.
Which Other Cars Share the SLK350’s Engine?
The M272 3.5-liter V6 engine wasn’t limited to the SLK350. Mercedes-Benz employed it in a range of their vehicles, allowing them to leverage economies of scale and maintain consistency across their product lines.
Here’s a table highlighting some of the other models that utilized the same engine:
| Model | Years | Notes |
|---|---|---|
| C-Class (W204) | 2007-2011 | C350 models |
| E-Class (W211, W212) | 2006-2011 | E350 models |
| CLS-Class (C219, C218) | 2006-2011 | CLS350 models |
| S-Class (W221) | 2006-2011 | S350 models |
| ML-Class (W164, W166) | 2006-2011 | ML350 models |
| R-Class (W251) | 2006-2011 | R350 models |
Why Share Engines?
Sharing engines across multiple models is a common practice in the automotive industry. This allows manufacturers to reduce development and production costs.
- Cost Reduction: Developing a new engine is a costly and time-consuming process. Using a shared engine amortizes these costs across a larger volume of vehicles.
- Parts Availability: Sharing engines simplifies parts logistics and maintenance, as dealerships and service centers can stock a smaller range of parts to service a wider variety of vehicles.
- Manufacturing Efficiency: Using a common engine platform streamlines manufacturing processes and reduces complexity in the assembly line.
