Mercedes-Benz unveiled the 2027 Mercedes EQS sedan with a 120 kWh battery pack. It delivers 470 miles EPA range, up 15% from prior 408 miles. Road & Track detailed upgrades like AI steer-by-wire steering.
Mercedes builds the prismatic NCM (nickel-cobalt-manganese) pack at Sindelfingen starting Q3 2026. Base price hits $112,000 USD. Scalability builds on past facelifts, per Reuters.
120 kWh Pack Boosts Range 15%
Mercedes raises usable capacity from 108 kWh to 120 kWh. Prismatic cells hit 280 Wh/kg and 700 Wh/L, per Mercedes specs and IEC 62660-1 tests.
EPA rates 470 miles per charge. Highway efficiency reaches 3.0 mi/kWh. Liquid cooling holds 95% round-trip efficiency at 80% DoD and 1C rate.
Ola Källenius, Mercedes-Benz Group CEO, said on a press call: "This positions the EQS as a long-haul luxury EV with grid integration potential."
AI Steer-by-Wire Trims Energy 8%
The 2027 EQS uses production steer-by-wire sans mechanical links, as Wired covered in EQXX prototypes. AI predicts inputs for torque vectoring.
Neural networks trained on 10 million miles cut highway energy use 8%. Ratios hit 4:1. System enables Level 3 autonomy per SAE J3016.
Markus Schäfer, Mercedes-Benz CTO, stated: "AI optimizes maneuvers to cut battery drain and boost range."
22 kW V2G Enables Grid Revenue
EQS handles 22 kW bidirectional AC charging. AI schedules discharges for peak V2G demand. BloombergNEF sees 50 GW V2G by 2030.
ISO 15118-20 supports smart charging. Trials yield 10 kWh daily per vehicle at 95% overnight SOC. PG&E eyes fleet pilots; Mercedes partners ChargePoint.
Jessica Caldwell, Edmunds analysis head, noted: "Bidirectional tech turns EVs into distributed storage."
Recycling Fuels Supply Chain Shift
Packs use 80% recycled cathode materials, per Mercedes sustainability report. Firm invests $5 billion USD in European gigafactories by 2028. Northvolt supplies from Skellefteå.
Silicon anodes push cycle life to 2,000 at 80% DoD. Degradation stays under 10% after 200,000 miles. BloombergNEF eyes 300 Wh/kg premium EV average by 2027.
IEA lists lithium at $15,000 USD/tonne in Q1 2024. Mercedes hedges 70% supply to 2028 with Albemarle and SQM contracts.
V2G Unlocks 100 GW Grid Buffer
EQS V2G aids frequency regulation and peak shaving. AI predicts solar curtailment for dispatches. California ISO models 1 million EVs offsetting 5 GW peaks by 2030.
NREL tests show 92% V2G efficiency. OTA updates enable FERC Order 2222 wholesale markets.
Phil Goodwin, S&P Global Mobility analyst, said: "Luxury EVs lead V2G with $0.08 USD/kWh LCOS."
$112,000 Price Targets Premium Buyers
EQS 450+ starts at $112,000 USD. IRA credits cut costs 30% for qualifiers, up to $7,500 USD. Lease at $1,200 USD/month over 36 months.
Argus Media pegs five-year TCO 20% below diesel S-Class. Kelley Blue Book shows 65% resale after 36 months. Predictive maintenance cuts downtime 15%.
Mercedes aims for 50,000 US sales yearly, scaling to 200,000 global by 2028 at 25% luxury EV CAGR.
500,000 Test Miles Validate Durability
Prototypes logged 500,000 miles in Death Valley and Arctic under ISO 16750-3. AI preconditioning retains 98% capacity at -20°C. 350 kW DC adds 200 miles in 15 minutes.
Steer-by-wire uptime tops 99.999%. AI reduces tire wear 12% with adaptive damping.
EVs as Storage Tackle Renewables
2027 Mercedes EQS turns 120 kWh packs into grid assets via V2G. Q3 2026 production scales to 10 GWh annually, fighting renewable intermittency.
