The Audi A4 is quite stylish, and it has great handling. Put these two things together and you have an attractive sports sedan. The A4 feels and looks like a luxury vehicle, and it comes in three different trims to give people the opportunity to choose the level of sophistication they'd like to see in their cars.

New for 2021 is a mild hybrid system that adds a little horsepower. This hybrid system comes on both powertrains available in the Audi A4. While most people won't be able to tell a difference between last year's engine and this year's engine, which has 13 more horsepower, this addition to the A4 illustrates how quickly Audi is adapting and incorporating innovations in its models.

Before going into the details regarding each trim, it may be beneficial to quickly go over the dimensions of the A4. It has a size and shape typical of a compact sedan, with a trunk that has a volume of 12 cubic feet. Leg room in the second row is 35.7 inches, so most adults would fit fine back there.

Another notable point is that all of the 2021 Audi A4 cars come with all-wheel drive. Audi's system is called quattro all-wheel drive, and it allows power to be delivered to all four wheels. As necessary, like when there's any loss of traction or when the car is taking a turn at a high speed, there can be a shift in how power is sent to the wheels. Those wheels that can use it the most will receive the power they need, right when they need it.

Compare the 2021 Audi A4 Premium 40 TFSI vs Premium 45 TFSI Trims. What is the Difference?

These two models are mostly the same, with the biggest differences being related to their capabilities. The 40 TFSI model is the more basic version, with 236 pound-feet of torque and just over 200 horsepower. This is certainly sufficient for most people, even those who love to push their cars to their limits, given the compact size of the Audi sedan. The engine in the 40 TFSI is a two-liter model with four cylinders, and as mentioned above, there's also a 12-volt battery providing some extra juice.

In the 45 TFSI model, there's the exact same engine. Some slight differences in the mechanical components result in more horsepower and more torque. Torque is nearly 275 pound-feet and horsepower is over 260, so there is definitely a lot of power here.

How do these numbers translate into something that some customers can more easily understand? Well, there's a significant difference in how fast these cars can hit the 60-mph mark. The 40 TFSI can go from zero to 60 in about 6.3 seconds. In contrast, the 45 TFSI can reach that speed in only 5.2 seconds. In reality, most people would be fine with either, but remember that we're talking about a luxury vehicle that's being marketed towards drivers with high expectations. Improvements in performance could play a major factor in which trims customers end up selecting.

There are a few other ways in which these Premium trims are distinct from one another. On first glance, some people may immediately notice that the 45 TSFI has larger wheels than the 40 TFSI does. It rides on 18-inch wheels, which have a five-double-spoke design, whereas the more basic trim have 17-inch wheels with a 10-spoke design. Both trims have LED headlights and taillights, and the dynamic turn signals on those taillights can attract a lot of attention. The dual exhaust outlets add to the sporty nature of the A4, and the aluminum window trim helps the car shine.

Both of these trims have upscale cabins, complete with power sunroofs and leather seats. Those seats are heated in the front, and they're also power-adjustable. The 45 TFSI has sport seats in the first row, and this model has power-adjustable lumbar support in both the driver's and passenger's seats. A few more enhancements in the 45 TFSI are notable. It has a sleek black headliner, illuminated door sills, and modern gray oak inlay for its interior trim.

Handling is superb in both the 40 and 45 trim at the Premium level. This is partly thanks to high-quality suspension systems and a seven-speed dual-clutch transmission. Audi uses an S tronic transmission system to make the car very responsive. The result is a thrilling experience when accelerating onto a highway, driving on curvy mountain roads, or simply running errands around town.

Compare the 2021 Audi A4 Premium 45 TFSI vs Premium Plus 40 TFSI Trim Levels. What is the Difference?

This matchup is a good one because it allows prospective customers to see what's so special about the Premium Plus level. Remember that this particular comparison is comparing the Premium trim with the better engine against the Premium Plus trim with the standard engine. Interestingly, the Premium Plus 40 TFSI is about three thousand dollars more expensive than the Premium 45 TFSI, so the upgrades should be expected to be somewhat significant.

Starting with the exterior of the sedan, it's clear that the Premium Plus has some more enhancements. Its headlights have a unique design, and its wheels have a bold, bi-color finish to them. Those wheels have ten spokes versus the Premium's five spokes.

The cabin of the Premium Plus 40 TFSI isn't that different from the Premium 45 TFSI. In fact, the Premium Plus 40 TFSI doesn't even have the sport seats or black headliner that were previously mentioned. What it does have, though, is important.

The safety and technology packages on the Audi A4 Premium Plus 40 TFSI are significantly nicer than what's found on the Premium 45 TFSI. The Premium Plus has a 360-degree camera that gives drivers a top-down view of their cars in relation to objects around them. This can help a lot with parking, just like the Parking System Plus can. Parking System Plus uses sensors to determine whether the Audi is getting too close to others, and it can alert drivers to potential problems. There's also a rear cross traffic alert system that can come in handy when someone is backing out of a parking spot.

Other advanced safety components included with the Premium Plus model, but not the Premium model, are blind spot monitoring, lane assist, and adaptive cruise control. With these technologies, the car can help the driver stay in a safe position, relative to the lane markings and other vehicles. Rather than just warning the driver about a lane departure like the Premium does, the Premium Plus can gently correct steering to recenter the vehicle. It's always reassuring to know that there's an extra pair of eyes looking out for issues, and it's even nicer to know that a car can take corrective measures when necessary.

The Premium Plus's Audi phone box is a fun, high-tech feature. It might not look like more than a compartment to store a phone, but it's actually a wireless charging pad and a signal booster. It uses the car's antenna to boost the signal and improve reception. Then, there's the virtual cockpit in the Premium Plus. It's a digital instrument cluster that can be customized according to the driver's preferences, and since it measures 12.3 inches and comes in full color, it's easy to read.

Compare the 2021 Audi A4 Premium Plus 40 TFSI vs Premium Plus 45 TFSI. What is the Difference?

The differences between these two trims are the same as the differences between the Premium 40 TFSI and the Premium 45 TFSI. It mostly comes down to horsepower, torque, and acceleration, and there are a few stylistic changes when moving to the 45 model as well. These have all been detailed in a previous section.

Compare the 2021 Audi A4 Premium Plus 45 TFSI vs Prestige 40 TFSI Trims. What is the Difference?

Moving up to the Prestige 40 TFSI from the Premium Plus 45 TFSI requires an extra $4,300. Since it's actually a downgrade in terms of capability, people may be wondering how Audi justifies this price increase.

The exterior of the Prestige is a good place to start. It has even nicer headlights than the ones in the Premium Plus. Those headlights have a matrix design and even come with their own washers to stay clean. Further, the headlights are animated, as are the taillights, and this is sure to leave a great impression with anyone who comes across these on the road.

While sitting in the front row of the Prestige, the driver and front passenger can enjoy heated and ventilated front seats. Just like the ones in the Premium Plus, they have the sport-style design to enhance the aesthetic in the cabin. The rear passengers get a little attention in the Prestige as well, since they also get to take advantage of heated seats.

Besides these enhancements, there are more functional upgrades in the Premium trim. Park Assist is a futuristic system that allows the Audi can park itself. Through the use of various sensors, the car can determine the size of a parking space and figure out how to steer itself into that spot. All the driver has to do is control the speed, letting the car take care of everything else. Park Assist works for both perpendicular and parallel parking, and it can even steer someone out of a parking spot. People driving Premium Audi A4s will no longer have to worry about getting nicks or scratches while parking, as they'll be able to be perfectly positioned every time.

The Prestige can treat people to a premium sound system; it comes with a Bang & Olufsen speaker system. 19 speakers and a 16-channel amp work together to produce studio-quality sound. Plus, navigation is standard at this level. These days, many people are specifically looking for vehicles with integrated navigation so that they can
always stay on track. Audi's navigation system can take traffic into account when giving people turn-by-turn directions.

When driving the Prestige 40 TFSI, people can stay aware of their surroundings, which may include important traffic signs. The car can read traffic signs that it passes and send that information to the head-up display. This display projects certain information onto the windshield so that it's directly in the driver's line of sight. Drivers can be reminded, gently, of changing speed limits or other key factors that might affect the choices they make.

Compare the 2021 Audi A4 Prestige 40 TFSI vs Prestige 45 TFSI. What is the Difference?

What the Prestige 45 TFSI brings is the added horsepower and torque. The differences between the 45 and 40 models at the Prestige level are the same as the differences between the two models at the lower trims.

Which Trim to Choose?

If people are seriously considering getting A4s, then they likely have healthy enough budgets to treat themselves. They'll be nicely rewarded with the 2021 Audi A4, which feels sporty and modern.

If budget isn't too much of a concern for a potential customer, the Audi A4 Prestige 45 TFSI is the recommended choice. It has the advanced capabilities that can make driving a little more exhilarating, and it comes with all the high-tech features that are so convenient to use. Navigation, a premium sound system, and a head-up display are all sought after, and they're great additions to the A4. Further, a self-parking feature and a 360-degree camera view are some examples of features that take things to the next level with the Prestige 45 TFSI.
