The 4 Series Coupe’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The TT doesn’t offer pre-crash pretensioners.

The 4 Series Coupe has standard City Collision Mitigation, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The TT doesn't offer collision warning or crash mitigation brakes.

Over 200 people are killed each year when backed over by motor vehicles. The 4 Series Coupe offers optional Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The TT doesn’t offer backup collision prevention brakes.

The 4 Series Coupe’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The TT doesn’t offer a lane departure warning system.

To help make backing out of a parking space safer, the 4 Series Coupe’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The TT doesn’t offer a cross-path warning system.

The 4 Series Coupe’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The TT doesn’t offer a driver alert monitor.

Both the 4 Series Coupe and the TT have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, post-collision automatic braking systems, daytime running lights, blind spot warning systems, rearview cameras and available all wheel drive.

Warranty

BMW pays for scheduled maintenance on the 4 Series Coupe for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the TT.

There are over 15 percent more BMW dealers than there are Audi dealers, which makes it easier should you ever need service under the 4 Series Coupe’s warranty.

Reliability

J.D. Power and Associates rated the 4 Series Coupe second among compact premium cars in their 2021 Initial Quality Study. The TT isn’t in the top three in its category.

J.D. Power and Associates’ 2021 Initial Quality Study of new car owners surveyed provide the statistics that show that BMW vehicles are better in initial quality than Audi vehicles. J.D. Power ranks BMW 20th in initial quality. With 74 more problems per 100 vehicles, Audi is ranked 32nd.

J.D. Power and Associates’ 2021 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that BMW vehicles are more reliable than Audi vehicles. J.D. Power ranks BMW 10th in reliability, above the industry average. With 19 more problems per 100 vehicles, Audi is ranked 20th.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that BMW vehicles are more reliable than Audi vehicles. Consumer Reports ranks BMW 2 places higher in reliability than Audi.

Regenerative brakes improve the 4 Series Coupe’s fuel efficiency by converting inertia back into energy instead of wasting it. The TT doesn’t offer a regenerative braking system.

Regardless of its engine, the 4 Series Coupe’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The TT RS doesn’t offer an automatic engine start/stop system.

The 4 Series Coupe has 1.1 gallons more fuel capacity than the TT (15.6 vs. 14.5 gallons), for longer range between fill-ups.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the BMW 4 Series Coupe higher (5 to 7 out of 10) than the Audi TT (3 to 7). This means the 4 Series Coupe produces up to 24.5 pounds less smog-producing pollutants than the TT every 15,000 miles.

Transmission

An eight-speed automatic is standard on the BMW 4 Series Coupe, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the TT.

Brakes and Stopping

For better stopping power the 4 Series Coupe’s standard brake rotors are larger than those on the TT:

	4 Series Coupe	TT
Front Rotors	13 inches	12.3 inches
Rear Rotors	13 inches	11.8 inches

The 4 Series Coupe’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the TT 45 TSFI are solid, not vented.

The 4 Series Coupe stops shorter than the TT:

	4 Series Coupe	TT
70 to 0 MPH	148 feet	157 feet	Car and Driver

Tires and Wheels

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the 4 Series Coupe can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The TT doesn’t offer run-flat tires.

Suspension and Handling

For a smoother ride and more stable handling, the 4 Series Coupe’s wheelbase is 13.6 inches longer than on the TT (112.2 inches vs. 98.6 inches).

For better handling and stability, the track (width between the wheels) on the 4 Series Coupe is .5 inches wider in the front and 2.8 inches wider in the rear than the average track on the TT.

The 4 Series Coupe’s front to rear weight distribution is more even (51.7% to 48.3%) than the TT’s (60.7% to 39.3%). This gives the 4 Series Coupe more stable handling and braking.

Chassis

The design of the BMW 4 Series Coupe amounts to more than styling. The 4 Series Coupe offers aerodynamic coefficients of drag from .25 to .3 Cd (depending on bodystyle and options). That is lower than the TT (.32 to .355). A more efficient exterior helps the 4 Series Coupe go faster and keeps the interior quieter. It also helps the 4 Series Coupe get better fuel mileage.

Passenger Space

The 4 Series Coupe has 12 cubic feet more passenger volume than the TT (86 vs. 74).

The 4 Series Coupe has .9 inches more front headroom, .7 inches more front legroom, 1.5 inches more front shoulder room, 1.4 inches more rear headroom, 5.6 inches more rear legroom and 3.1 inches more rear shoulder room than the TT Coupe.

Cargo Capacity

Pulling a handle automatically lowers the 4 Series Coupe’s rear seats, to make changing between passengers and cargo easier. The TT doesn’t offer automatic folding seats.

With its coupe body style, valet key, locking rear seatbacks and remote trunk release lockout, the 4 Series offers cargo security. The TT’s non-lockable folding seat and non-lockable remote release defeat cargo security.

To make loading and unloading groceries and cargo easier, especially for short adults, the 4 Series Coupe offers an optional power trunk, which opens and closes automatically by pressing a button, or optionally by just waving your foot, completely leaving your hands free. The TT doesn’t offer a power trunk.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that BMW service is better than Audi. J.D. Power ranks BMW 8th in service department satisfaction (above the industry average). With a 4% lower rating, Audi is ranked 12th.

Ergonomics

The 4 Series Coupe offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The TT doesn’t offer a remote starting system.

When two different drivers share the 4 Series Coupe, the memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, outside mirror angle, climate settings and radio stations. The TT doesn’t offer a memory system.

The 4 Series Coupe offers an optional heads-up display that projects speed, tachometer, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The TT doesn’t offer a heads-up display.

While driving with high beams on, sensitive light sensors standard on the 4 Series Coupe detect other vehicles which could be blinded and automatically switch to low beams. The TT doesn’t offer automatic dimming high beams.

The TT’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The 4 Series Coupe’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the 4 Series Coupe has standard extendable sun visors. The TT doesn’t offer extendable visors.

Optional air-conditioned seats in the 4 Series Coupe keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The TT doesn’t offer air-conditioned seats.

On extremely cold winter days, the 4 Series Coupe’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The TT doesn’t offer a heated steering wheel.

The 4 Series Coupe has a standard center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable and it can provide a boundary between children. The TT doesn’t offer a rear seat center armrest.

The 4 Series Coupe’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The TT doesn’t offer dual zone air conditioning.

For greater rear passenger comfort, the 4 Series Coupe has standard rear a/c vents to keep rear occupants more comfortable. The TT doesn’t offer rear vents.

To keep a safe, consistent following distance, the 4 Series Coupe offers an optional Active Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The TT doesn’t offer an adaptive cruise control.

Model Availability

The BMW 4 Series comes in coupe, convertible and four door hatchback bodystyles; the Audi TT isn’t available as a four door.

The 4 Series Coupe is available in both rear-wheel drive and all-wheel drive configurations. The TT doesn’t offer a two-wheel drive configuration.

Economic Advantages

Insurance will cost less for the 4 Series Coupe owner. The Complete Car Cost Guide estimates that insurance for the 4 Series Coupe will cost $1830 less than the TT over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the BMW 4 Series Coupe will be $2593 to $6500 less than for the Audi TT.

Recommendations

The BMW 4 Series outsold the Audi TT by over 20 to one during the 2021 model year.
