Main differences between the 2018 Volvo S90 and 2018 BMW 5 Series
The decisive differences are ride/handling character, engine ladder, rear-seat space, and standard equipment. The S90 rides softer, includes more driver-assist tech out of the box, and affords superior back-seat room thanks to its long wheelbase.
The BMW 5 Series turns in with more precision, offers a broader power range (including V8 M550i), and generally retains higher resale. Infotainment philosophies differ too: Volvo’s portrait touchscreen versus BMW’s iDrive with rotary/touch/gesture controls.
Similarities and common ground
Both use 8-speed automatics, offer a plug-in hybrid variant, and provide a full suite of luxury options like premium audio, advanced seating, and adaptive lighting. Each can be configured as a quiet highway cruiser with strong active-safety support.
Both carry 4-year/50,000-mile new-vehicle warranties and included scheduled maintenance coverage on 2018 models, though coverage terms and what’s included can differ by brand and program year.
Price, comparable trims and feature‑adjusted value
When new in 2018, a Volvo S90 T5 undercut a BMW 530i by roughly a few thousand dollars at base MSRP, and Volvo packed in more standard driver-assist features. Moving up trims, S90 T6 typically priced against well-equipped 530i or lightly optioned 540i.
On today’s used market, comparable S90s commonly list for less than like‑mileage 5 Series models. If you value comfort, safety kit, and space more than top-end performance, the S90 often wins on feature‑adjusted value.
- Premium fuel is recommended for most engines in both lineups.
- PHEVs add home charging needs; battery warranties typically 8yr/100k mi (U.S. federal minimum for EV components).
- Performance tires and brakes on 540i/M550i can raise running costs versus S90 T5/T6 touring setups.
Size, seating, cargo and everyday practicality
Volvo’s 2018 S90 long wheelbase delivers outstanding rear legroom, making it a favorite for passengers and chauffeured use. Entry/egress and outward visibility are excellent for a low sedan.
The BMW 5 Series provides adequate rear space for adults but focuses more on driver position and front-seat ergonomics. PHEV trunks (S90 T8 and 530e) are slightly smaller than their gasoline siblings due to battery packaging.
Interior comfort, visibility and cabin usability
The 2018 Volvo S90 emphasizes calm ergonomics, superb seat comfort, and a minimalist Scandinavian design. Materials feel upscale even on lower trims, with quietness that rewards long commutes.
The BMW 5 Series tilts driver-centric with firm, supportive seats and extensive adjustability, especially with the Multi‑Contour option. It’s still quiet and refined, but tuned to keep the driver more engaged behind the wheel.
- Back-to-back the same road: compare steering effort and road feel at 35–55 mph.
- Repeat a rough-pavement loop to sense ride isolation (S90 often feels softer).
- Try the rear seats if you carry adults often; legroom differences are stark.
- Demo adaptive cruise/lanekeeping on both to judge smoothness and trust.
Infotainment, controls and technology
Volvo’s Sensus 9-inch portrait touchscreen centralizes most functions. It’s clean and supports Apple CarPlay and Android Auto when optioned, plus robust Volvo On Call app features. Some owners prefer physical controls for climate and drive modes.
BMW iDrive 6.0 mixes a rotary controller, touchscreen, and available gesture control. Apple CarPlay was optional and subscription-based on many 2018 builds; Android Auto was not available that year. If smartphone mirroring matters, verify the exact BMW configuration.
If you’re weighing broader brand safety approaches, see this background explainer on Volvo safety versus other cars, which helps frame why Volvo often makes more driver-assist tech standard.
Safety and driver assistance
Both cars offer automatic emergency braking, adaptive cruise, blind-spot monitoring, lane-keeping assistance, and more. In 2018, the S90 made many systems standard (including Pilot Assist), while the 5 Series required specific option packages for similar coverage.
On crash testing, both earned strong IIHS results for the 2018 model year when properly equipped. NHTSA rated the 2018 5 Series at five stars overall; the 2018 S90 did not have a comparable NHTSA overall rating published at the time of writing.
IIHS ratings can depend on headlights and front-crash-prevention options. Confirm your car’s exact headlight type and AEB package, and compare only across the same agency/protocol and model years for apples-to-apples results.
For a focused look at the question many shoppers ask, our guide on which car is safer, Volvo or BMW explains how to interpret equipment and scores across model years.
Performance, ride, handling and drivetrain
The S90 T5 and T6 are smooth and punchy, with the T6’s super‑and‑turbo 2.0L delivering confident passing power. The T8 plug‑in hybrid is the quickest S90, blending strong electric torque with eAWD traction.
The BMW 5 Series responds more eagerly to inputs and scales performance higher. The 540i’s inline‑six is notably refined and quick, while the M550i xDrive reaches genuine high-performance territory beyond anything in the S90 range.
Fuel economy and plug‑in range
EPA combined fuel economy for 2018 gas variants clusters closely: think mid‑20s mpg for most configurations, with driveline and wheel choices nudging results. In practice, the 530i and S90 T5 are similar; the 540i and S90 T6 trade a bit of efficiency for speed.
Plug‑in models differ more in character than raw numbers. The S90 T8 typically offers about 21 miles of EPA‑rated EV range and serious system power, while the 530e offers around 16 miles of EV range and a more efficiency‑focused demeanor.
Reliability, known issues and evidence level
Both nameplates land near the luxury‑class average in most large-sample reliability snapshots, with variations by engine and options. Hybrids add complexity but also carry separate component warranties.
Use official recall databases and service bulletins for car‑specific checks. Owner‑reported issues tend to center on software updates, electronics, and wear items; severity and frequency vary by maintenance history and build.
Maintenance, insurance, depreciation and total ownership cost
Both brands included scheduled maintenance on 2018 cars (coverage content can differ). Insurance can rise with higher-performance trims and expensive wheel/tire packages.
Depreciation typically favors the buyer on a used S90, which often transacts for less than a comparable 5 Series. That gap can offset higher option content on the BMW—run real numbers on the specific cars you’re comparing.
