BYD Sealion 07 DM-i

The BYD Sealion 07 DM-i is a mid-to-large-size plug-in hybrid SUV under the BYD Ocean Series, officially launched on 8 May 2025. Built on BYD's next-generation dedicated PHEV platform, it combines 5th-generation DM technology with advanced smart connectivity to deliver an ideal balance of high performance and long cruising range in the RM160,000 to RM200,000 SUV segment.

Vehicle Overview

Positioned as a mid-to-large SUV, the Sealion 07 DM-i incorporates BYD's signature "Ocean Aesthetics" design philosophy.

Market Tags: Mid-to-large SUV, 5th-generation DM technology, advanced smart driving, intelligent cabin, long range.

Product Highlights: Serving as a core model in BYD's PHEV stable, its main selling point is the 5th-generation DM plug-in hybrid system, achieving remarkably low depleted-battery fuel consumption and a combined range of up to 1,320 km on a full tank and full charge. Furthermore, the standard inclusion of the "Eye of the Gods" advanced driver assistance system (ADAS) and DiSus-C intelligent damping body control system across all variants significantly enhances tech capability and ride quality within its price class. 

Market Positioning: Primarily aimed at family buyers requiring long-distance touring capabilities and excellent fuel economy, serving as a strategic product to reinforce BYD's footprint in the spacious 5-seater SUV segment. 

Development History

Background: Within the Sealion 07 product lineup, BYD introduced the DM-i plug-in hybrid alongside the pure-electric EV version to cater to diverse charging needs, specifically targeting motorists without dedicated home charging facilities or those requiring long-distance travel capabilities.

Launch Milestone: On 8 May 2025, the Sealion 07 DM-i officially went on sale with a price range between RM169,800 and RM205,800. 

Key Highlights: As one of the debut models to feature 5th-generation DM technology, the Sealion 07 DM-i quickly garnered strong market attention in the family SUV segment, driven by its frugal 4.7 L/100 km depleted-battery fuel consumption (NEDC cycle) and a brisk 0-100 km/h acceleration of 4.7 seconds on the AWD variant. 

Market Performance

Competitive Landscape: Positioned in the heart of the RM150,000 to RM200,000 price band, this model competes against mid-size and mid-to-large SUVs from both within the brand and rival mainstream carmakers. Its market strengths lie in BYD's extensive aftersales network, strong value proposition derived from vertical supply chain integration, and an established track record in PHEV technology. 

Customer Reception: Owners have widely praised the "Ocean Rhythm" interior design, appreciating the uncluttered dashboard layout and premium materials. Family buyers have given high marks particularly to the generous rear legroom, practical boot capacity, and cruising stability over long journeys courtesy of the DiSus-C suspension system.

Core Technologies

Powertrain System: Powered by the 5th-generation DM powertrain, available in 2WD and AWD configurations. The AWD variant delivers a maximum electric motor output of 350 kW, achieving 0-100 km/h in just 4.7 seconds. Depleted-battery fuel consumption is rated as low as 4.7 L/100 km, with a CLTC pure electric range of up to 150 km and an overall combined range of 1,320 km.

Intelligent Equipment: All variants come standard with the "Eye of the Gods" intelligent driving assistance system, supporting City Navigation on Autopilot (NOA), Highway NOA, and Valet Parking Assist. In addition, the vehicle can be optioned with BYD's integrated vehicle-mounted drone system—"Lingyuan"—supporting one-touch takeoff, vehicle-follow tracking, and synchronised ground-air filming to enhance lifestyle and recreational appeal. 

Chassis & Safety: The DiSus-C intelligent damping body control system is standard across the range, paired with a multi-link independent rear suspension to strike an optimal balance between performance, ride comfort, and handling. The chassis features a high-strength safety cell and 10 airbags as standard, meeting top-tier industry standards in both active and passive safety.

Future Plans

The strategic roadmap for the Sealion 07 DM-i focuses on: 

ADAS Algorithm Evolution: Delivering continuous over-the-air (OTA) updates to refine navigation-assisted driving under complex urban traffic conditions, further enhancing everyday driving convenience.

Overseas Market Adaptation: In line with BYD's global expansion, accelerating the R&D and vehicle homologation of export variants tailored to international regulatory and climatic requirements.

Continuous Powertrain Optimisation: Analysing real-world user data to continuously fine-tune the 5th-generation DM system's power management logic and thermal management strategies, maintaining its benchmark energy efficiency among plug-in hybrid SUVs in its class.
