As a mechanic, I’ve seen my fair share of impressive machines roll into the shop, but there are some cars that just stick with you. Back in 2006, while working at a local garage to fund my college years, I witnessed something special. It wasn’t the usual muscle car or flashy sports car; it was an Audi B7 RS 4. The sound was unlike anything I’d heard before, a raw, visceral roar that hinted at something extraordinary under the hood. Little did I know then, this car would become a benchmark for performance sedans, a testament to a bygone era of naturally aspirated engines and driver-focused engineering.

Fast forward almost two decades, and the 2007 Audi RS4 still holds a special place in the hearts of enthusiasts. It’s a car that represents a unique moment in automotive history, a bridge between analog driving experiences and the increasingly digital world of modern performance vehicles. Let’s delve into what makes the 2007 Rs4 such an enduring icon.
2007 Audi RS4: Performance That Still Thrills
Score: 7/10
The heart of the 2007 Audi RS4 is undoubtedly its engine. And where is that heart located? Perhaps a bit too far forward for perfect weight distribution purists might argue. Indeed, the placement of the engine in the B7 RS 4 is somewhat unconventional. It sits so far forward under the hood that it’s almost kissing the Audi badge on the grille. Compounded with the quattro all-wheel-drive system, this contributes to a front-heavy weight distribution, with around 60% of the car’s nearly 4,000 pounds resting over the front axle. Adding to the peculiar yet impressive engineering, the front brakes boast eight-piston calipers, borrowed straight from a Lamborghini Gallardo. Weird? Maybe. Glorious? Absolutely.
Engine: A Masterpiece of Natural Aspiration
The high-revving 4.2-liter V8 engine of the 2007 Audi RS4, a testament to naturally aspirated performance.
The engine in the 2007 RS4 is a 4.2-liter naturally aspirated V8 masterpiece. In an era dominated by turbocharging, this high-revving V8 is a breath of fresh air. It churns out a staggering 420 horsepower at a sky-high 7,800 RPM and 317 lb-ft of torque at 6,000 RPM. These figures might not sound groundbreaking by today’s standards, but the way this power is delivered is what sets it apart. It’s an engine that’s incredibly smooth throughout the rev range, offering instant throttle response and a linear power build-up that’s almost extinct in the turbocharged era.
One common misconception is that the RS4 is an untamed beast, requiring constant attention and a racing helmet for even mundane tasks. This couldn’t be further from the truth. In normal driving conditions, the 2007 Audi RS4 is as docile and comfortable as any other Audi A4. The engine remains subdued, and ample torque is available right off the bat for effortless city driving. However, unleash the full potential of this V8, and it transforms into a different animal. Plant your foot, and the engine eagerly climbs through the revs, delivering a spine-tingling soundtrack and exhilarating acceleration. Unlike some high-performance engines that are peaky or require specific conditions to shine, the RS4’s V8 feels potent and responsive at any point in the rev range. It’s derived from the R8 supercar, a pedigree that speaks volumes about its capabilities.
While the factory exhaust note is refined, many enthusiasts opt for an aftermarket exhaust system to truly let this engine sing. An upgraded exhaust amplifies the V8’s natural voice, turning the RS4 into an auditory experience that complements its driving prowess.
Transmission: A Manual Gearbox That Demands Engagement
The six-speed manual transmission of the 2007 Audi RS4, offering a direct connection to the car’s performance.
Moving away from the engine, the six-speed manual transmission in the 2007 RS4 is a mixed bag. It’s a manual, which is a huge plus for purists, but it’s not without its quirks. The throws are quite long, almost requiring a full arm extension to shift from first to second gear. The clutch engagement is also abrupt, biting quickly and low to the floor. While this directness is appreciated in performance driving, it can take some getting used to in daily use.
Despite these criticisms, rowing through the gears in the RS4 is still an enjoyable experience. It’s a reminder of a time when driver engagement was paramount. And for those who might be seeking an automatic… well, there isn’t one. The 2007 Audi RS4 was exclusively offered with a manual transmission, solidifying its driver-focused nature.
Steering and Chassis: Surprisingly Agile Despite its Weight
Despite the front-heavy weight distribution, the 2007 Audi RS4 handles remarkably well. While it might not be the ultimate track weapon due to its inherent understeer characteristics from the quattro system and engine placement, it’s far more capable than its weight and layout might suggest. Where the engine placement truly becomes noticeable is at the absolute limit on a track, something most owners are unlikely to explore regularly.
On public roads, the RS4 feels surprisingly agile and well-balanced. Turn-in is crisp, and the car feels planted and stable in corners. The quattro all-wheel-drive system is a major asset, providing immense grip and allowing you to confidently apply power even in challenging conditions. You can essentially mash the throttle mid-corner, and the car intelligently distributes power to maximize traction and maintain composure.

The suspension setup is fixed, with no electronic adjustability, yet it strikes an excellent balance between comfort and performance. It’s firm enough to provide excellent body control in corners but supple enough to absorb road imperfections without being jarring. The hydraulic power steering is another highlight, offering natural and progressive feedback that builds with steering effort and speed. For younger drivers accustomed to electric power steering systems, experiencing the hydraulic steering in the RS4 is a revelation, offering a level of feel and connection that’s often missing in modern cars.
Brakes: Italian Stopping Power
The braking system in the 2007 RS4 is another area where Audi went above and beyond. Taking advantage of their ownership of Lamborghini, they equipped the RS4 with massive eight-piston Brembo calipers up front, sourced from the Lamborghini Gallardo. While the rotor sizes (14.4-inches front, 12.8-inches rear) aren’t the largest, the sheer clamping force of the multi-piston calipers provides impressive stopping power.
The brake pedal feel is generally good, although there’s a slight initial delay upon first application. For street use, the brakes are more than adequate, offering strong and consistent performance. However, for sustained track use in hot conditions, particularly given the car’s weight, some might desire even more robust braking performance.
2007 Audi RS4: Utility and Practicality
Score: 6/10
In terms of practicality, the 2007 Audi RS4 is a sedan, and while sedans have lost ground to SUVs and wagons in recent years, they still offer a compelling blend of passenger space and cargo capacity. The RS4 is no exception.
The rear seats of the 2007 Audi RS4, offering decent space for passengers in a performance sedan package.
The rear seats are somewhat compact, typical for cars of this era and class. Legroom in the back can be a bit tight for taller adults, making it more suitable for shorter journeys or smaller passengers. However, for four adults, the RS4 is perfectly usable.
One notable drawback in terms of utility is the seat height. The driver’s seat sits quite high, and even at its lowest setting, headroom can be limited, especially for taller drivers. This might be a deal-breaker for some, as it compromises the driving position and overall comfort.
2007 Audi RS4: Fuel Economy – Let’s Be Realistic
Score: 5/10
Fuel economy is not a strong suit of the 2007 Audi RS4, but let’s be honest, if you’re considering a high-performance V8 sedan, fuel efficiency is likely not your top priority. The EPA estimates for the RS4 are 17 MPG combined, with 14 MPG in the city and 21 MPG on the highway. Real-world figures are likely to be in this ballpark, depending on driving style.
Considering the 420 horsepower V8 and all-wheel-drive system, these figures are somewhat understandable. It’s a thirsty engine, especially when driven with enthusiasm, which is hard to resist. However, compared to modern performance cars, even with advancements in technology, the RS4’s fuel consumption isn’t drastically worse than some of its contemporaries.
2007 Audi RS4: Features and Comfort – A Blend of Sport and Luxury
Score: 7/10
The 2007 Audi RS4 falls into that interesting category of “tweener” cars – not quite old enough to be considered vintage, but not new enough to feel entirely modern. It’s in that transitional phase where some features feel dated, while others have aged gracefully.
Interior: Timeless Audi Quality

Inside, the 2007 RS4 showcases classic Audi design and quality. The leather upholstery is supple and luxurious, and the scent of high-quality leather still permeates the cabin even after years. Real carbon fiber trim accents the interior, adding a sporty touch that was ahead of its time.
The instrument cluster is clear and functional, with simple digital readouts that are surprisingly crisp and legible, even compared to some modern economy cars. The navigation system, however, is undeniably outdated and essentially unusable by today’s standards. Apple CarPlay and Android Auto are, of course, not available. However, in a car like the RS4, perhaps getting lost and taking the scenic route is part of the charm.
The shifter, while functional, feels somewhat generic, reminiscent of those found in more pedestrian Volkswagen models. The placement of the electronic parking brake, requiring lifting the center armrest to engage, is an odd ergonomic quirk. Despite these minor flaws, the interior of the 2007 RS4 is a pleasant and well-built environment.
Exterior: Muscular and Understated Aggression
The muscular yet refined exterior styling of the 2007 Audi RS4, a perfect blend of sportiness and elegance.
The exterior styling of the 2007 RS4 is a masterclass in understated aggression. It’s not overtly flashy, but the widened fenders, subtle body kit, and signature RS badging hint at the performance lurking beneath the surface. Sprint Blue is a particularly striking color option that highlights the RS4’s muscular lines. Matte silver mirror caps and trim pieces add a touch of sophistication and contrast. The overall design has aged remarkably well, retaining a timeless appeal that still turns heads today.
2007 Audi RS4 vs. the Competition: A Unique Proposition
The 2007 Audi RS4 arrived on the scene to challenge the BMW E9x M3. While the M3, which came out a bit later, might be considered the more dynamically focused and ultimately faster car, the RS4 offered a unique driving experience that was equally compelling. The RS4’s naturally aspirated V8, quattro all-wheel-drive, and distinctive styling created a formula that resonated with enthusiasts.
Compared to the Mitsubishi Lancer Evo MR, as mentioned in a period review, the RS4 is in a different league in terms of refinement, luxury, and overall driving experience. While the Evo was a raw and capable performance machine, the RS4 offered a more sophisticated and well-rounded package.
The 2007 Audi RS4, despite its initial high price tag, has become a sought-after classic in the used market. It represents a unique blend of high-revving naturally aspirated V8 power, manual transmission engagement, and all-weather quattro confidence, all wrapped in a stylish and practical sedan body. It’s a car that deserves to be celebrated and driven, a reminder of a golden era of performance sedans that are increasingly rare in today’s automotive landscape. No electric Audi, no matter how fast, will ever replicate the visceral thrill of revving the 4.2-liter V8 to its 8,250 RPM redline.
