Audi has become well known for building some of the best turbocharged engines that offer power and fuel efficiency to entice and excite a large crowd of luxury car owners. The Audi A4 is certainly one that falls squarely into this category with a massive amount of luxury features and performance equipment to enjoy. In stiff competition with well-known and often lauded luxury vehicles such as the BMW 3 Series, Cadillac CTS and Inifiniti Q50 the Audi A4 has to be a top performer and it certainly has the goods to make the others quake in their boots as it flies on by.

Providing top performing characteristics the A4 and S4 models offered by Audi create a duo that is hard for any other car to compete with or beat. For 2015 the A4 and S4 add a few minor improvement to make this awesome car even a bit better including adding the S style package as standard equipment on all A4’s, a 60/40 split rear seat, headlight washers and a tri-zone climate control all make the list of standard features for the A4 and S4 to keep all competition at bay.

The drive of an A4 sedan offers a very smooth and supple ride that is also highly performance laden. This is easily achieved with the inclusion of the top of the line suspension that laughs at road abrasions and defects keeping the occupants smoothly riding along and enjoying the cruise. Throw in a steering that is so responsive that any minor input from the driver is delivered and responded to instantly and without any hint of hesitation. Of course this is a luxury sedan so a quiet cabin must be in place the Audi A4 is no exception to the rule here having a cabin that doesn’t allow any outside noises to enter in and cause disturbance of the enjoyment of the ride.

It may seem two cars are being discussed in this article, but it’s actually the same car, just one is the sport version. For the A4 the engine offered is an extremely well-designed 2.0-liter turbocharged inline four-cylinder engine that puts out 220 horsepower and 258 lb.-ft. of torque. This engine can be mated to three different transmissions and for the front-wheel drive models the automatic continuously variable transmission allows the car to achieve a fuel economy of 24 city/32 hwy mpg. Moving to the all-wheel drive models brings in the six-speed manual transmission that achieves 22 city/32 hwy mpg and the eight-speed automatic that reaches up to 22 city/31 hwy mpg making this not only a powerful powertrain, but one that offers a nice amount of fuel efficiency as well.

The S4 is powered by a 3.0-liter supercharged V6 engine that is just awesome with power and hungry to be unleashed on the open road. This engine comes in with 333 horsepower and 325 lb.-ft. of torque to take this luxury car quickly around any highway curves or shoot it across the straightaways. This engine is mated to either the automatic transmission bringing in a fuel mileage of 18 city/28 hwy mpg or the manual transmission that offers 17 city/26 hwy mpg of fuel economy to enjoy. Both engines are directly injected adding to the fantastic engineering that is at play here.

From inside the cabin the A4 is simple but amazing. Every inch of this great sedan has been well-designed and thought out in detail and then done again. The materials throughout are very upscale and the interior room is amazing allowing anyone riding along to get comfortable in their seats. Trimmed out in metal and wood the interior shows interest at every angle allowing drivers to be amazed by the feel, comfort, design and pleasure of the ride inside the cabin.
