Which Mercedes-Benz Vehicles Still Offer a V6 or V8 in 2025

If you’re hunting for a Mercedes-Benz with a V6 or V8 engine in 2025, here’s something crucial to know: Mercedes has completely ditched V6 engines across their entire passenger car lineup this year. What you’ll find instead are inline-6 engines as their six-cylinder option, plus a carefully selected group of V8-powered flagship models and AMG® performance variants.

This shift changes the game for luxury car shopping, particularly if you’re someone who values traditional multi-cylinder performance. At Mercedes-Benz of Tyler, we help East Texas buyers work through these powertrain changes to find what actually fits their driving style. Whether you’re after the smooth refinement of an inline-6 or the thunderous power of a V8, knowing what’s out there puts you in the driver’s seat when making decisions.

2025 Mercedes-Benz Powertrains: What’s Changed and What Hasn’t

Mercedes keeps tweaking their engine lineup to satisfy tougher emissions rules while keeping the performance and luxury the brand built its reputation on. Turbocharged engines are now standard across most models, letting the company squeeze impressive power from smaller engines while boosting fuel economy.

The 2025 lineup breaks down into three main powertrain camps. Turbocharged inline-4 engines run most models, including the C-Class, base E-Class, and compact SUVs like the GLA, GLB, and GLC. Inline-6 engines show up in higher-trim models such as the GLE, GLS, E-Class All-Terrain, and select AMG® variants. V8 engines stay exclusive to flagship models and performance-focused AMG® versions.

Most of these engines now include mild-hybrid or plug-in hybrid tech. This setup creates smoother operation, better efficiency, and extra electric punch when you need it. The change reflects Mercedes’ push toward electrification while keeping the driving dynamics that enthusiasts actually care about.

Why Mercedes-Benz Moved Away from V6 Engines

Killing off V6 engines was a calculated engineering choice. Inline-6 engines run smoother and more balanced than V6 setups because all cylinders line up straight instead of forming a V-shape. This layout cuts down vibrations and creates a more polished driving feel.

Inline-6 engines also fit better under the hood and work more seamlessly with turbocharging systems. From an emissions perspective, this configuration helps Mercedes meet strict environmental regulations without gutting the performance that buyers expect from a six-cylinder.

The move follows a broader industry shift toward downsizing and turbocharging. By fine-tuning engine design, Mercedes keeps power output strong while improving fuel efficiency and cutting environmental impact. For buyers in East Texas who put serious miles on their cars and want reliable performance, inline-6 engines deliver many of the perks traditionally linked with V6 power while offering technical advantages.

Luxury Sedans and SUVs with Inline-6 Options

The E-Class All-Terrain packs an inline-6 engine with all-wheel drive, creating a capable luxury wagon that handles different driving conditions well. Base GLE and GLS SUV models also use inline-6 power, often combined with mild-hybrid systems to optimize performance and efficiency.

Higher-trim S-Class variants offer inline-6 options alongside their V8 and V12 powertrains. These engines provide the smooth, refined power you’d expect from a flagship sedan while delivering better gas mileage than larger engines.

For buyers who want balanced performance and efficiency, these inline-6 models hit the sweet spot. They offer more power than turbocharged four-cylinder alternatives while getting better fuel economy than V8 engines. The smoothness built into the inline-6 design creates a refined driving experience that matches Mercedes-Benz’s luxury reputation.

2025 Mercedes-Benz Models with V8 Engines

V8 engines still exist in select 2025 models, but they’re saved for flagship luxury vehicles and high-performance AMG® variants. This exclusivity reflects Mercedes’ strategy to position V8 power as the peak of performance and prestige.

The V8 engines across the lineup feature twin-turbocharging and advanced tech to maximize power while managing emissions. Many include mild-hybrid systems that boost efficiency without killing the visceral driving experience that V8 fans crave.

High-Performance AMG® V8 Models

The AMG® lineup shows the brand’s dedication to traditional performance with its 4.0-liter twin-turbocharged V8 engine. This powerplant appears in multiple configurations across various models, cranking out exceptional horsepower and torque.

The SL-Class keeps V8 power in its SL 63 and higher variants, with output hitting up to 577 horsepower. This setup maintains the roadster’s performance heritage while adding modern efficiency tech. The twin-turbo configuration provides instant throttle response and sustained power delivery through the rev range.

The AMG® Pure Speed concept vehicle features a 4.0-liter V8 biturbo engine producing around 585 horsepower. This demonstrates Mercedes-AMG®’s continued commitment to high-output V8 performance despite the industry’s march toward electrification.

Select GLE and GLS AMG® variants keep V8 availability for buyers who want maximum performance in an SUV package. These engines turn luxury SUVs into genuine high-performance machines capable of impressive acceleration and serious towing capacity.

V8-Powered Luxury SUVs and Sedans

The S-Class S 580 4MATIC® Sedan features a 4.0-liter twin-turbocharged V8 making 496 horsepower, paired with a mild-hybrid system. This combination delivers the commanding power you’d expect from a flagship sedan while incorporating efficiency-boosting technology.

The Maybach S 580 uses the same 4.0-liter V8 mild-hybrid powertrain, creating an ultra-luxurious driving experience with serious power reserves. For buyers wanting even more exclusivity, the S 680 variant offers a V12 engine option.

These V8-powered models represent the traditional luxury sedan experience at its peak. The engines provide effortless acceleration, confident highway passing power, and the refinement that comes from eight cylinders working together. For East Texas drivers who regularly cover long distances on open highways, this combination of power and smoothness makes V8 sedans especially attractive.

Comparing Inline-6 vs V8 Performance in 2025 Mercedes-Benz Models

Picking between inline-6 and V8 power comes down to your priorities and how you actually drive. Both setups offer distinct advantages that work for different types of buyers.

Power Output and Driving Dynamics

V8 engines deliver superior absolute power, with outputs ranging from nearly 500 horsepower in base configurations to well over 570 horsepower in AMG® applications. This means thrilling acceleration, confident high-speed cruising, and substantial towing capacity when you need it.

Inline-6 engines provide solid performance on their own, typically producing between 360 and 430 horsepower depending on the application. While they can’t match V8 output, these engines deliver smooth, linear power that feels effortless in everyday driving. The natural balance of the inline-6 design creates minimal vibration, contributing to a refined cabin experience.

The weight difference between engine configurations affects how cars handle. Inline-6 models typically feel more nimble in corners due to less weight over the front axle, while V8 models deliver a sense of planted stability and commanding road presence. Both approaches work well depending on your driving style.

Fuel Economy and Operating Costs

Inline-6 engines generally get better fuel economy than V8 alternatives, especially on the highway where their efficiency advantages really show. The combination of turbocharging and mild-hybrid tech helps these engines optimize fuel use during cruising.

V8 engines drink more fuel, particularly during aggressive driving or frequent acceleration. However, advances in turbocharging and cylinder deactivation technology have closed the gap somewhat. Modern V8 engines manage fuel consumption much better than older generations.

Operating costs go beyond just gas. V8 engines typically cost more to maintain due to added complexity and more parts. Inline-6 engines generally cost less to service over time, though both benefit from Mercedes-Benz’s engineering quality and reliability.

If you’re planning to keep your car for many years, these cost factors matter. When fuel economy and lower operating costs rank high on your list, inline-6 power makes financial sense. If maximum performance comes first and fuel costs don’t worry you as much, V8 engines deliver uncompromising capability.

Which Models No Longer Offer V6 or V8 Engines

Several popular Mercedes-Benz models have switched exclusively to four-cylinder or inline-6 power for 2025, dropping previous V6 or V8 options.

The entire C-Class range, including AMG® trims, now runs on turbocharged inline-4 engines. Despite fewer cylinders, these powertrains use advanced mild-hybrid and direct-injection technology to deliver competitive performance and efficiency.

E-Class models feature turbocharged inline-4 engines in base trims, with the All-Terrain variant getting inline-6 power. You won’t find V8 options in the E-Class lineup for 2025.

Compact SUVs including the GLA, GLB, and GLC use turbocharged inline-4 engines exclusively. Mercedes positions these models as efficient luxury choices where six or eight cylinders aren’t necessary for their intended purpose.

Base GLE and GLS models feature turbocharged inline-6 engines with mild-hybrid assist. V8 power in these SUVs stays reserved for AMG® variants only, making eight-cylinder performance a premium upgrade rather than a standard choice.

The Inline-6: Mercedes-Benz’s New “V6 Alternative”

The inline-6 engine represents Mercedes’ response to buyer demand for six-cylinder power. While technically different from a V6, the inline-6 delivers similar displacement and power output while offering mechanical advantages.

In an inline-6 configuration, all six cylinders line up in a straight row. This creates perfect primary and secondary balance, resulting in exceptionally smooth operation without the vibrations common in V6 designs. The layout also allows for better turbocharger placement and superior cooling characteristics.

V6 engines arrange six cylinders in two banks forming a V-shape. While compact, this configuration naturally creates more vibration than an inline layout. Mercedes’ decision to favor inline-6 design prioritizes refinement and engineering efficiency over saving space under the hood.

For buyers used to V6 power, the switch to inline-6 brings real benefits. The smoothness rivals traditional V8 engines in some ways, creating a luxury driving experience that meets Mercedes standards. Combined with turbocharging and hybrid assist, inline-6 engines deliver performance that satisfies most drivers who don’t need absolute maximum power.

Which Mercedes-Benz V6 or V8 is Right for Your Needs?

Finding the right powertrain starts with honest assessment of how and where you actually drive.

V8 power makes sense if you’re a performance enthusiast who values traditional multi-cylinder grunt, you want maximum acceleration and passing power, you frequently tow heavy loads, or you prioritize the prestige of flagship models. If you value long-term ownership of conventional engines before full electrification takes over, V8 models represent increasingly rare options that may hold special appeal.

Inline-6 engines work well for buyers seeking balanced performance and efficiency, those who value refinement and smoothness over raw power, environmentally conscious drivers who still want more than four cylinders, and buyers who prioritize lower long-term operating costs while keeping strong performance.

For East Texas driving conditions, both powertrains work well. V8 performance suits the region’s long highway stretches and hot climate, where substantial power reserves and confident cruising capability enhance the driving experience. The commanding presence and effortless acceleration make V8 models particularly satisfying for frequent long-distance travel between Tyler and other Texas cities.

Inline-6 models deliver plenty of power for the same driving conditions while providing better fuel economy for daily commuting. The smoothness and refinement make them suitable luxury choices that don’t sacrifice the premium feel Mercedes buyers expect.
