2026 BMW 740i Features & Specs

For the discerning driver in East Tennessee, the 2026 BMW 740i represents the golden mean of the luxury flagship segment. While the V8-powered 760i grabs headlines, the six-cylinder 740i remains the definitive executive sedan, offering a powertrain architecture that balances inherent smoothness with sufficient torque for the gradients of the Great Smoky Mountains.
At Grayson BMW, we see the 740i not as the "entry" model, but as the purest expression of the sports sedan DNA that defines the brand. Here is a technical breakdown of why this specific configuration is uniquely suited for Knoxville roads.
The B58 Power Plant: Inline-6 Perfection.
The heart of the 2026 BMW 740i is the B58 3.0-liter BMW TwinPower Turbo inline-6 engine. Unlike V6 configurations used by competitors, an inline-6 design is inherently balanced, canceling out primary and secondary engine vibrations without the need for heavy counter-balancing shafts.
For 2026, this combustion engine is augmented by a 48-volt mild-hybrid system. An electric motor is integrated directly into the 8-speed Steptronic transmission, adding an immediate torque fill during the initial phase of acceleration before the turbocharger reaches peak boost.

Chassis Engineering for Tennessee Roads.
Knoxville's infrastructure presents a mix of tight downtown streets and sweeping mountain highways. The 2026 BMW 740i addresses this dichotomy with a standard two-axle air suspension featuring automatic self-leveling. This system monitors wheel movement hundreds of times per second, adjusting damper firmness to absorb the pothole-riddled pavement of the Old City while stiffening up for stability on the Tail of the Dragon.
Critical for local parking garages, the available Integral Active Steering (rear-axle steering) reduces the turning circle to just 39.7 feet. At low speeds, the rear wheels turn opposite the front, effectively shortening the wheelbase and allowing this 212-inch sedan to maneuver like a 3 Series.
Digital Cockpit and The Interaction Bar.
The interior of the 2026 740i moves beyond traditional luxury buttons. The dashboard is dominated by the BMW Curved Display, which fuses a 12.3-inch Digital Instrument Cluster and a 14.9-inch Central Information Display behind a single, continuous glass surface.
Below this lies the BMW Interaction Bar, a crystalline surface structure with touch-sensitive controls that spans the entire width of the dashboard and extends into the door panels. It is not merely decorative; it provides visual feedback for hazard lights, incoming calls, and exit warnings, integrating safety directly into the ambient lighting design.
Executive Rear Seating Dimensions.
The 2026 740i is designed to accommodate adults comfortably, whether for a lunch meeting in Bearden or a trip to Nashville. The rear cabin offers 43.3 inches of legroom and 56.3 inches of shoulder room, ensuring passengers can cross their legs without contacting the front seatbacks.
Behind the seats, the trunk provides 19.1 cubic feet of cargo volume. This is a distinct advantage over the plug-in hybrid competitors, where battery placement often intrudes on luggage space.
