2027 BMW 5 SERIES VS. 2027 MERCEDES-BENZ E-CLASS: FULL COMPARISON.
BMW 530i and Mercedes-Benz E 350 both produce 255 hp and 295 lb-ft of torque from turbocharged four-cylinder engines, but their drivetrains, fuel economy, cargo capacity, technology, and available powertrains differ. BMW 530i returns 29 MPG city and 35 MPG highway, compared with 25 MPG city and 33 MPG highway for the rear-wheel-drive Mercedes-Benz E 350. Below is a specification-by-specification comparison of the 2027 BMW 5 Series and 2027 Mercedes-Benz E-Class, with current 2027 BMW 5 Series inventory available at Grayson BMW in Knoxville.
THE SHORT ANSWER.
BMW 5 Series may suit shoppers who prioritize fuel economy, cargo capacity, multiple gasoline powertrains, and a plug-in-hybrid model outside the full BMW M lineup.
Mercedes-Benz E-Class offers its own combination of mild-hybrid powertrains, MBUX technology, available 4MATIC all-wheel drive, and an available AMG plug-in hybrid.
At the entry level, BMW 530i and Mercedes-Benz E 350 have identical horsepower and torque figures. BMW 530i provides higher EPA-estimated city and highway fuel economy, a larger trunk, and slightly quicker manufacturer-estimated acceleration.
The better fit depends on the drivetrain, technology, comfort equipment, and powertrain configuration each shopper prefers.

PERFORMANCE AND POWERTRAIN.
BMW 530i and Mercedes-Benz E 350 begin with closely matched output. BMW 530i uses a 2.0-liter BMW TwinPower Turbo inline four-cylinder producing 255 hp and 295 lb-ft of torque. An eight-speed automatic transmission sends power to the rear wheels. BMW 530i reaches 60 mph in 5.9 seconds and carries preliminary EPA-estimated fuel economy of 29 MPG city, 35 MPG highway, and 31 MPG combined. BMW 530i xDrive retains the same engine while adding BMW xDrive all-wheel drive. BMW 540i xDrive steps up to a 3.0-liter BMW TwinPower Turbo inline six-cylinder producing 375 hp and 398 lb-ft of torque. BMW xDrive is standard, and 0-60 mph takes 4.4 seconds. BMW 550e xDrive combines a 3.0-liter BMW TwinPower Turbo inline six-cylinder with an electric motor for 483 hp and 516 lb-ft of combined output. It also provides up to 33 miles of estimated all-electric range under ideal conditions.
Mercedes-Benz E 350 uses a 2.0-liter turbocharged inline four-cylinder with mild-hybrid assistance, producing 255 hp and 295 lb-ft of torque. A 9G-TRONIC nine-speed automatic transmission is standard. Rear-wheel-drive Mercedes-Benz E 350 reaches 60 mph in 6.1 seconds and is rated at 25 MPG city and 33 MPG highway. Mercedes-Benz E 350 4MATIC adds all-wheel drive and carries a 24 MPG city and 33 MPG highway rating. Mercedes-Benz E 450 4MATIC uses a 3.0-liter turbocharged inline six-cylinder with mild-hybrid technology, producing 375 hp and 369 lb-ft of torque. It reaches 60 mph in 4.4 seconds. Mercedes-AMG E 53 HYBRID provides the plug-in-hybrid option within the E-Class family.
BMW 5 Series powertrain details
FUEL ECONOMY.
At the comparable rear-wheel-drive four-cylinder level, BMW 530i has the fuel-economy advantage.
BMW 530i.
- 29 MPG city
- 35 MPG highway
- 31 MPG combined
MERCEDES-BENZ E 350.
- 25 MPG city
- 33 MPG highway
That gives BMW 530i a four-MPG advantage in city driving and a two-MPG advantage on the highway.
BMW 530i xDrive and Mercedes-Benz E 350 4MATIC should be compared separately because both add all-wheel drive and carry different fuel-economy ratings from their rear-wheel-drive counterparts.
INTERIOR, SPACE, AND CARGO.
Both sedans seat five passengers.
BMW 5 SERIES DIMENSIONS.
BMW 5 Series measures 199.2 inches long, 74.8 inches wide excluding mirrors, and 59.6 inches high.
MERCEDES-BENZ E-CLASS DIMENSIONS.
Mercedes-Benz E-Class measures 194.9 inches long, 74 inches wide excluding mirrors, and 57.9 inches high.
The difference in exterior length should not automatically be interpreted as a direct measurement of rear-seat room, because passenger-space dimensions depend on interior packaging as well as overall body size.
CARGO CAPACITY.
BMW 5 Series provides 18.3 cu ft of trunk capacity and a folding rear seat for additional cargo flexibility.
Mercedes-Benz E-Class provides 12.7 cu ft of trunk capacity and uses a 40:20:40 split-folding rear seatback.
The BMW therefore provides 5.6 cu ft more stated trunk capacity, while both vehicles allow longer cargo to extend into the passenger compartment by folding portions of the rear seat.
Available comfort equipment on both sedans varies by model and configuration, so shoppers should compare individual vehicles rather than assuming every comfort feature is standard across an entire lineup.
TECHNOLOGY AND INFOTAINMENT.
BMW 5 SERIES TECHNOLOGY.
BMW 5 Series uses BMW Operating System 8.5 with BMW Curved Display.
Core technology includes:
- BMW Operating System 8.5
- BMW Curved Display
- BMW Intelligent Personal Assistant
- Wireless Apple CarPlay
- Wireless Android Auto
- BMW ConnectedDrive
- Remote Software Upgrade capability
- My BMW App integration
Additional BMW technology can include BMW Head-Up Display, BMW Digital Key Plus, upgraded parking systems, expanded camera views, premium audio, and additional driver-assistance equipment depending on configuration.
MERCEDES-BENZ E-CLASS TECHNOLOGY.
Mercedes-Benz E-Class uses third-generation MBUX and a 14.4-inch central multimedia display.
Its technology can include features such as:
- Wireless Apple CarPlay and Android Auto
- MBUX profiles and routines
- MBUX Augmented Video for Navigation
- Available third-party applications
- Mercedes-Benz Digital Extras
- Digital Vehicle Key
- Available MBUX Superscreen
The two systems take different approaches to cockpit design. BMW Operating System 8.5 integrates BMW vehicle functions through BMW Curved Display and QuickSelect, while MBUX places significant emphasis on its central touchscreen, profiles, routines, and available digital applications.
Neither approach makes one system universally better for every shopper. A test drive is the best way to determine which interface feels more intuitive.
BMW 5 Series technology and safety features
SAFETY AND DRIVER ASSISTANCE.
BMW 5 SERIES DRIVER ASSISTANCE.
BMW 5 Series includes standard driver-assistance technology such as Active Blind Spot Detection, Lane Departure Warning, and Frontal Collision Warning with City Collision Mitigation.
Additional available BMW systems can provide:
- Distance control
- Steering assistance
- Lane-change support
- Stop-and-go assistance
- Expanded highway-driving assistance
- Additional parking cameras
- Automated parking functions
MERCEDES-BENZ E-CLASS DRIVER ASSISTANCE.
Mercedes-Benz E-Class includes its own standard driver-assistance and collision-mitigation systems, while additional technology is available through equipment packages.
For example, Active Distance Assist DISTRONIC is available rather than universally standard on the 2027 Mercedes-Benz E 350.
Both manufacturers offer additional Level 2 driver-assistance functionality depending on configuration.
These systems assist the driver but do not replace the driver's responsibility to monitor traffic, road conditions, and vehicle operation.
BMW 550e xDRIVE VS. AMG E 53 HYBRID.
Both lineups offer plug-in-hybrid capability, but the models occupy different positions within their respective families.
BMW 550e xDrive is part of the core BMW 5 Series Sedan lineup.
It combines a 3.0-liter BMW TwinPower Turbo inline six-cylinder with an electric motor for:
- 483 hp
- 516 lb-ft of torque
- BMW xDrive all-wheel drive
- 0-60 mph in 4.1 seconds
- Up to 33 miles of estimated all-electric range
Mercedes-AMG E 53 HYBRID is an AMG performance model rather than the direct equivalent of Mercedes-Benz E 350.
Shoppers primarily interested in adding plug-in-hybrid capability without moving into a full BMW M model can therefore consider BMW 550e xDrive within the core BMW 5 Series lineup.
VALUE AND OWNERSHIP.
BMW 5 Series is covered by the BMW New Vehicle Limited Warranty for four years or 50,000 miles.
BMW Ultimate Care also includes eligible scheduled maintenance for three years or 36,000 miles.
Mercedes-Benz E-Class includes a four-year/50,000-mile New Vehicle Limited Warranty.
Warranty coverage is therefore similar in duration at the new-vehicle level, while included maintenance programs differ between manufacturers.
Fuel expense depends on annual mileage, driving conditions, fuel prices, and specific model. BMW 530i's higher EPA-estimated fuel economy can reduce gasoline consumption compared with Mercedes-Benz E 350 under otherwise similar driving conditions, but actual savings will vary.
