- 2027 EQS achieves 522-mile EPA range with 118 kWh battery.
- Steer-by-wire cuts weight 20% with redundant safety.
- AI saves 8% energy via traffic prediction.
Mercedes-Benz unveiled the 2027 EQS on April 14, 2026 (CET), achieving 522-mile EPA range with steer-by-wire and AI features. CEO Ola Källenius announced it from Stuttgart, Germany. Production starts late 2026 at Sindelfingen, targeting global EV markets.
522-Mile Range Sets New EV Benchmarks
The 2027 Mercedes-Benz EQS delivers 522 miles per charge, up 18% from the 2025 model's 443 miles, per Mercedes-Benz Group AG's 2025 annual report. Advanced silicon-carbide semiconductors from Wolfspeed boost efficiency 12%, said Markus Schäfer, Member of the Board of Development at Mercedes-Benz Group AG.
The 118 kWh battery uses lithium-iron-phosphate cells from CATL in Ningde, China. This cuts weight 15% versus nickel-manganese-cobalt packs, linking Chinese factories to German lines. Norway's EV sales hit 92% of new vehicles in 2025, per state data, aligning with EU zero-emission mandates by 2035. U.S. interstates benefit from fewer charging stops.
Steer-by-Wire Replaces Mechanical Steering
Steer-by-wire uses electronic actuators and sensors, eliminating the steering column. The wheel retracts in Level 3 autonomy. Redundant systems passed safety tests over 1.2 million miles on Germany's Autobahn (CET), per Wired.
The system weighs 20% less than mechanical setups, per Mercedes data. TSMC in Taiwan supplies control chips, affecting U.S. and Asian EV production.
AI Turns 2027 Mercedes-Benz EQS into Smart Global Platform
AI predicts traffic 500 meters ahead, saving 8% energy. MBUX Hyperscreen neural networks train on 10 billion driving miles, Källenius noted.
Voice AI supports 27 languages, from Hindi in Mumbai to Spanish in Mexico City. Monthly OTA updates run on AWS servers in Frankfurt (CET). TechCrunch reported Mercedes AI needs 25% fewer interventions than Tesla's Full Self-Driving. Resale values rise USD 5,000 on range gains.
Mercedes shares (MBG.DE) climbed 3.2% to EUR 68.50 on Xetra in Frankfurt on April 14, 2026 (CET). Lithium prices rose 7% in Australia.
Global Supply Chains Drive EQS Production
China supplies 65% of batteries, per Bloomberg. CATL's Jiangxi plants ramp output despite U.S. tariffs. Li Xiang, CATL executive vice-president, confirmed expanded capacity for Mercedes.
Northvolt's Skellefteå gigafactory in Sweden adds 10 GWh yearly, cutting Asia reliance 22%. Hungary plants follow. EV batteries support grid storage, stabilizing demand in Texas and Europe.
Longer Range Cuts Emissions, Boosts Finance
The range reduces lifetime emissions 14% versus rivals, per University of Michigan's Volker Sick in Nature Energy. Vehicle-to-grid tech feeds 5 kW to homes.
IEA data show 18 million global EV sales in 2025. The 2027 Mercedes-Benz EQS aids Paris Agreement targets. India's Gujarat drivers praise AI flood avoidance. Vietnam benefits from grid stability.
Policies and Rivals Accelerate EV Race
EU approved steer-by-wire under UN ECE R79. U.S. NHTSA tests Level 4 in Arizona.
Mercedes invests USD 1.2 billion in AI. BMW and Audi target 500 miles by 2028, per analyst Oliver Zipse of BMW.
BYD ships 450-mile sedans to Brazil, pressuring prices 10% lower. Rotterdam ports handle Shanghai exports. Mercedes EV revenue reached USD 28 billion in 2025, matching Tesla.
Blockchain traces Congo materials for ethics.
Next: Range tests end April 30, 2026 (CET). Deliveries start Q4 2026 in Europe, Q1 2027 in U.S. and Asia. Annual output targets 200,000 units of the 2027 Mercedes-Benz EQS.
