The R8 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Senna doesn’t offer all-wheel drive.

The R8 has standard Audi Connect CARE, which uses a global positioning satellite (GPS) receiver and a cellular system to send emergency personnel to the scene if any airbags deploy. The Senna doesn’t offer a GPS response system, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the R8 and the Senna have standard driver and passenger frontal airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and daytime running lights.

The Audi R8 weighs 486 to 630 pounds more than the McLaren Senna. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.


The R8 comes with a full 4-year/50,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Senna’s 3-year basic warranty expires 1 year sooner.

The R8’s corrosion warranty is 2 years longer than the Senna’s (12 vs. 10 years).

There are almost 16 times as many Audi dealers as there are McLaren dealers, which makes it much easier should you ever need service under the R8’s warranty.

Fuel Economy and Range

In heavy traffic or at stoplights the R8’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Senna doesn’t offer an automatic engine start/stop system.

The R8 has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Senna doesn’t offer a cap-less fueling system.


All wheel drive, available in the R8, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The McLaren Senna is not available with all wheel drive.

Tires and Wheels

The R8’s optional tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the Senna’s 35 series front tires.

For better ride, handling and brake cooling the R8 offers optional 20-inch wheels. The Senna’s largest wheels are only 19-inches in the front and 20-inches in the rear.

The Audi R8’s wheels have 5 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The McLaren Senna only has 1 wheel lugs per wheel.

Suspension and Handling

For better maneuverability, the R8’s turning circle is 5.6 feet tighter than the Senna’s (36.7 feet vs. 42.3 feet).


The R8 is 1 foot shorter than the Senna, making the R8 easier to handle, maneuver and park in tight spaces.


When different drivers share the R8, the memory system makes it convenient. Each keyless remote activates different, customized memories for the driver’s seat position and climate settings. The Senna doesn’t offer a memory system.

The R8’s standard power window controls are mounted on the armrest for easy access. The Senna’s available power window controls are spread out on the center console where they can’t be seen without the driver completely removing his eyes from the road.

While driving with high beams on, sensitive light sensors standard on the R8 detect other vehicles which could be blinded and automatically switch to low beams. The Senna doesn’t offer automatic dimming high beams.

To direct the driver from any location to a given street address, a GPS navigation system is standard on the R8. The R8’s navigation system also has a real-time traffic update feature that offers alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Senna doesn’t offer a navigation system.

Model Availability

The Audi R8 comes in coupe and convertible bodystyles; the McLaren Senna isn’t available as a convertible.
