How to Choose Q5 Engines
When selecting Q5 engines for your inventory or recommending them to customers, several factors should be considered to ensure the best match for specific needs and applications.
Performance Considerations
Evaluate power requirements based on customer driving habits:
- The 2.0 TFSI (248-261 hp) is ideal for daily commuting and general use
- The 3.0 TFSI V6 (349 hp) suits performance enthusiasts and those who demand quick acceleration
- The 2.0 TFSI e hybrid (362 hp combined) offers the best of both worlds – efficiency and power
Efficiency and Cost Factors
Balance initial cost against long-term operating expenses:
- 2.0 TFSI engines typically return 22-24 mpg city, 28-30 mpg highway
- 3.0 TFSI V6 engines average 18-20 mpg city, 23-26 mpg highway
- 2.0 TFSI e hybrid can achieve 65 MPGe with electric-only range of approximately 19 miles
| Selection Factor | Importance | Considerations |
|---|---|---|
| Power & Performance | High | Match engine power to customer driving habits and expectations |
| Fuel Efficiency | High | Consider daily driving distances and fuel costs in customer's region |

Q5 Engine FAQs
The Audi Q5 2.0 TFSI engine is a turbocharged four-cylinder engine that serves as the base powerplant for most Q5 models. It generates 261 horsepower and 273 lb-ft of torque in current models. This engine combines direct fuel injection technology with turbocharging to deliver strong acceleration while maintaining reasonable fuel efficiency. The TFSI designation stands for "Turbocharged Fuel Stratified Injection," highlighting Audi's advanced fuel delivery system.
The Audi Q5 2.0 TFSI e engine is a plug-in hybrid powertrain that combines a 2.0-liter turbocharged four-cylinder engine with an electric motor. Together, they generate a combined 362 horsepower and 369 lb-ft of torque. This hybrid system provides impressive acceleration (0-60 mph in approximately 5.0 seconds) while offering an all-electric driving range of about 19 miles. The "e" designation indicates the electrified nature of this powertrain, which features a 14.1 kWh lithium-ion battery pack integrated into the vehicle.
The Audi Q5 3.0 TFSI V6 engine is a high-performance 3.0-liter V6 engine with 48V mild hybrid technology that generates 349 horsepower and 369 lb-ft of torque. This powerful engine allows the SQ5 variant to accelerate from 0-60 mph in just 4.7 seconds. The V6 configuration provides smoother operation than four-cylinder alternatives, while the mild hybrid system enhances efficiency by allowing for extended start-stop functionality and energy recuperation during braking.
The Audi Q5 2.0 TFSI quattro engine combines the standard 2.0-liter turbocharged four-cylinder engine (261 hp, 273 lb-ft) with Audi's quattro all-wheel drive system. This intelligent AWD system continuously monitors driving conditions and can send power to the wheels with the most traction. In normal driving conditions, it operates primarily in front-wheel drive for efficiency, but can instantly distribute up to 100% of available torque to the rear wheels when needed, providing enhanced handling and stability on various road surfaces and weather conditions.
The Audi Q5 2.0 TFSI S line uses the same 2.0-liter turbocharged four-cylinder engine (261 hp, 273 lb-ft) as standard Q5 models, but comes in the S line trim package. This includes sport-tuned suspension with firmer damping characteristics for improved handling, distinctive S line exterior styling elements (unique front and rear bumpers, side sills, and badging), and S line interior upgrades (sport seats, brushed aluminum trim, and a sport steering wheel with paddle shifters). While the engine specifications remain identical to the standard Q5, the S line package enhances the vehicle's sporty character through these suspension and aesthetic modifications.
