Engine and Powertrain: The Heart of Performance

At the core of any performance comparison lies the engine and its supporting powertrain. Both the CLS and A7 offer a range of engine options, often with a focus on smooth power delivery and impressive torque. However, Mercedes-Benz often pushes the boundaries further with its AMG variants, delivering truly supercar-levels of performance.

Mercedes-Benz CLS Class Powertrains

The CLS Class offers a spectrum of powerful engines. Standard models often feature potent inline-six or V8 engines, providing ample power for effortless cruising and spirited acceleration. However, the true performance heart of the CLS lineup beats within its AMG iterations.

AMG CLS 53 4MATIC+: Typically powered by a potent turbocharged inline-six engine combined with Mercedes-AMG’s EQ Boost mild-hybrid system. This setup delivers robust horsepower and torque, offering rapid acceleration and instant throttle response. The mild-hybrid system provides a temporary power boost and enhances fuel efficiency.
AMG CLS 63 S 4MATIC+ (past generations, or future conceptually): Historically, the top-tier CLS models feature a hand-built AMG V8 engine. These powertrains are known for their immense power, thunderous exhaust notes, and relentless acceleration, offering a truly visceral driving experience.

All CLS models come equipped with advanced transmissions designed for smooth shifts and rapid engagement, often featuring multiple driving modes to tailor the powertrain’s response to your preference.

Audi A7 Powertrains

Audi’s approach to performance often involves sophisticated technology, with a strong emphasis on its signature quattro all-wheel drive.

A7 55 TFSI: This model often utilizes a potent turbocharged V6 engine, frequently supplemented by a mild-hybrid system (like Audi’s 48-volt mild-hybrid technology) to enhance efficiency and smooth out power delivery. This provides a strong balance of performance and everyday usability.
S7 TFSI: Stepping up, the S7 typically features a more powerful V8 engine, delivering a significant increase in horsepower and torque. This pushes the A7 into sports car territory, offering thrilling acceleration.
RS 7 Sportback: At the zenith of the A7 range, the RS 7 is a performance beast. It usually boasts a twin-turbocharged V8 engine, capable of producing supercar-rivalling horsepower. Its performance is designed to be both brutal and precise, thanks to advanced chassis and drivetrain technologies.

Audi’s S tronic dual-clutch transmissions are known for their lightning-fast shifts, contributing to the sporty feel of the A7 and its performance variants.

Performance Metrics: Numbers Don’t Lie (But Feel Does)

While engine specs are crucial, it’s the real-world performance metrics that often sway buyers. Acceleration, braking, and top speed tell a significant part of the story.

Acceleration (0-60 mph)

This is where the AMG variants of the CLS often shine brightly. Their focus on raw power means they can typically out-accelerate their Audi A7 counterparts, especially when comparing like-for-like AMG models against non-RS Audi variants.

Mercedes-Benz CLS (AMG CLS 53): Expect 0-60 mph times in the low 4-second range.
Mercedes-Benz CLS (AMG CLS 63 S – conceptual): These models have historically achieved 0-60 mph times well under 4 seconds, often in the mid-3-second range.
Audi A7 (A7 55 TFSI): Typically hovers around the mid-4-second range.
Audi A7 (S7 TFSI): Gets closer to the low to mid-3-second range.
Audi A7 (RS 7 Sportback): Competes directly with the highest-tier AMG CLS models, often achieving 0-60 mph times in the mid-to-low 3-second range.

Braking Performance

Both vehicles are equipped with high-performance braking systems designed to bring these powerful machines to a halt quickly and with confidence. While standard models will offer robust stopping power, the AMG and RS variants often feature larger, more advanced braking systems, including carbon-ceramic options, for track-ready performance. The specific feel of the brakes can differ, with some drivers preferring the sometimes firmer pedal of AMG brakes, while others appreciate the progressive feel of Audi’s setup.

Top Speed

While regulated in many markets, these cars are engineered for high-speed stability. AMG CLS models and Audi RS models are often electronically limited to 155 mph, but optional performance packages can raise this limit significantly, sometimes exceeding 180 mph or even 200 mph for the most potent iterations.

Handling and Dynamics: The Art of the Curve

Performance isn’t just about going fast in a straight line; it’s about how the car behaves when the road gets twisty. Here, the philosophies of Mercedes-Benz and Audi often diverge, offering distinct driving characters.

Mercedes-Benz CLS Class

The CLS Class, especially in its AMG guise, is engineered to provide a sporty and engaging driving experience.

Suspension: The CLS typically features a sophisticated multi-link suspension system. AMG models often boast performance-tuned air suspension (AIRMATIC or ACTIVE BODY CONTROL) that can adapt to driving conditions, offering a balance between comfort and sporty handling. It aims to keep the car flat and composed during hard cornering while absorbing road imperfections.
Steering: The steering in the CLS is generally direct and communicative, providing good feedback to the driver. AMG models often have variable-ratio steering that becomes quicker at higher speeds, enhancing agility.
Chassis Balance: While a larger car, AMG versions are meticulously engineered to offset weight and deliver a dynamic feel. Depending on the exact configuration, it can feel more rear-wheel-drive biased, offering a more playful, tail-happy character when pushed.
Traction: While some CLS models are RWD, the 4MATIC+ all-wheel-drive system in AMG variants is often rear-biased, allowing for controlled oversteer and sporty driving dynamics while still providing excellent traction when needed.

For enthusiasts, the CLS offers a more visceral connection to the road, a feeling of being part of the machine.

Audi A7

Audi’s approach to handling often prioritizes stability, refinement, and technological prowess, with its quattro all-wheel-drive system being a central pillar.

Suspension: The A7 typically employs a sophisticated multi-link suspension. Air suspension is often an option or standard on higher trims, allowing for adjustable ride height and damping. This system is renowned for its ability to blend a comfortable ride with composed handling.
Steering: Audi’s steering is known for its precision and smooth weighting. It feels planted and reassuring, offering confidence at all speeds. While perhaps not as raw as some AMG setups, it provides excellent control.
Chassis Balance: The A7, particularly with quattro, offers exceptional stability. It tends to feel incredibly planted and secure, even in adverse weather conditions. The power is distributed intelligently to maximize grip.
Traction: The permanent quattro all-wheel-drive system is a hallmark of Audi performance. It provides superb traction and grip, allowing drivers to accelerate hard out of corners with confidence. This makes the A7 a formidable performer, especially in wet or slippery conditions. For the sportiest A7 models like the RS 7, a torque-vectoring rear differential can further enhance agility and distribute power precisely to individual wheels.

The A7 offers a feeling of effortless competence and unwavering stability, making it a supremely capable grand tourer that inspires confidence.
