What's the real world gas mileage like for a 2012 Audi R8 V10?

Question

Accepted Answer

Based on my research, here's what you can expect for real-world gas mileage on a 2012 Audi R8 V10:

**Stock/Unmodified R8 V10 Manual:**
- EPA ratings: 12 mpg city / 19 mpg highway / 14 mpg combined
- Real-world owner reports: Most drivers see 11-16 mpg in mixed driving, with careful highway cruising potentially reaching 19-20 mpg

**This Modified Twin-Turbo R8:**
The Stage 1.5 twin-turbo conversion significantly increases power output to 1000+ WHP, but this comes at a considerable fuel economy cost. Based on industry data for turbocharged supercars, you can expect:
- **City driving:** 9-10 mpg (down from 12 mpg stock)
- **Highway cruising:** 14-15 mpg (down from 19 mpg stock)  
- **Combined real-world:** 10-12 mpg (down from 14 mpg stock)

The turbo system essentially adds 20-30% more fuel consumption under normal driving, and when you're in boost (which happens frequently with that much power), fuel economy can drop to single digits. This is typical for high-horsepower turbo builds where performance is prioritized over efficiency.
