Has Electricity Consumption Entered the Single‑Digit Era? Geely’s New E‑Drive Makes Its EVs Both Efficient and Spirited

[Source: Autohome Technology]

In today’s NEV market, 800V high‑voltage platforms and multi‑in‑one e‑drive units have become industry standards. Most mainstream players are competing with 8‑in‑1 or 12‑in‑1 solutions, focusing on fast‑charging speed, 0‑100 km/h acceleration, and energy efficiency. But that clearly feels like wanting to have your cake and eat it too – fast and frugal sounds like a contradiction.

Just yesterday, Geely unveiled its "Thunder 16‑in‑1 Intelligent E‑Drive", which debuts on the Galaxy TT pure‑electric sedan. At the same time, it set two Guinness World Records: “lowest energy consumption for a production BEV sedan around Qinghai Lake” and “longest continuous dual‑car drift on a wet surface.” The company claims this e‑drive pushes integration, efficiency, and durability to new heights – in short, it delivers both low consumption and strong performance. But is that really the case?

What is a 16‑in‑1 E‑Drive? Gimmick or Genuine Technology?

Many owners are unclear about the difference between 8‑in‑1, 12‑in‑1, and 16‑in‑1. Here’s a simple analogy: think of a fridge, TV, and washing machine as separate appliances, each with its own plug and wiring – taking up space and complicating the layout. If you integrated all three into one unit with a single power connection, you’d dramatically simplify the wiring and shrink the overall footprint. That’s the core logic behind multi‑in‑one integration.

Current mainstream solutions are 8‑in‑1 and 12‑in‑1. Geely’s 16‑in‑1 is like “integrating every household appliance and the entire intelligent management system into one all‑in‑one chassis.”

This high level of integration offers three key advantages:

1. Fewer components: The multi‑in‑one e‑drive eliminates over 180 sets of housings, wiring harnesses, and connectors, physically reducing the risk of ageing or poor connections.

2. Lighter weight and more space: The entire unit weighs only 75 kg and is under 325 mm in height. In the Galaxy TT, it frees up an extra 28 litres of boot space.

3. 800V architecture: Based on an 800V system, the higher voltage reduces current, cutting transmission losses by 80%.

In an industry comparison, the Tesla Model 3 uses an 8‑in‑1, Xpeng’s mainstream models have a 9‑in‑1, BYD and Huawei use 12‑in‑1, while Geely has advanced to 16‑in‑1 – placing it at the forefront of mass‑production integration.

However, it should be noted that more isn’t always better. A 16‑in‑1 design demands higher manufacturing precision and better electromagnetic interference shielding to avoid engineering pitfalls that come from “integrating for integration’s sake.”

Behind the Two Guinness Records: Balancing Efficiency and Performance

The industry has long faced a dilemma – strong acceleration and aggressive driving naturally consume more energy, while chasing low consumption usually means limiting power output. The Galaxy TT, with this 16‑in‑1 e‑drive, managed to claim both records.

93.8% combined efficiency and 8.2 kWh consumption – first, what does a CLTC combined efficiency of 93.8% mean? Currently, mainstream e‑drive efficiencies average between 90% and 92%. Theoretically, every 1% improvement in e‑drive efficiency reduces 100‑km energy consumption by about 1.5%. Geely’s 93.8% is the key to its impressive efficiency figures.

So why is it so energy‑saving? Technically, it relies on three major technologies:

• AI energy consumption algorithm: The system automatically selects the optimal operating range for three scenarios – high‑speed, winter, and congested traffic. In extreme cold down to ‑18°C, the AI thermal storage system can store the equivalent of 7 kWh of heat energy, helping to mitigate winter range loss.

Now let’s look at official test results: around Qinghai Lake, the car achieved 8.2 kWh per 100 km – that’s a C‑segment sedan with a 2,920 mm wheelbase delivering consumption comparable to a compact city car.

For the drift challenge, two major tests were faced: first, the torque needs to switch polarity in milliseconds, requiring real‑time power adjustments; second, the motor runs at sustained high RPM and temperature, which often triggers thermal derating and power loss. The Thunder 16‑in‑1 solution includes:

• Single‑chip integrated control: Traditional e‑drive signal transmission takes 40 ms; this system shortens it to as fast as 2 ms. Combined with an AI torque prediction algorithm, torque error is reduced from 3% to 1%, improving vehicle attitude control during extreme manoeuvres.

• 54‑channel targeted oil cooling: A 360° full‑coverage oil spray structure lowers the motor’s peak temperature by 15°C, ensuring stable power output during prolonged aggressive driving.

Objectively, drift tests don’t mirror everyday driving, but they do reveal the hardware limits of thermal management and torque control. In frequent real‑world scenarios like mountain overtaking, high‑speed emergency lane changes, or continuous climbing, this system offers greater safety margins. With a combined four‑wheel‑drive output of 425 kW and 0‑100 km/h in 3.8 seconds, it balances daily commuting with occasional spirited driving.

Final Thoughts

Based on current information, the Thunder 16‑in‑1 is not just a numbers game – it’s a holistic solution that integrates manufacturing techniques, high‑voltage efficiency, thermal control, and intelligent algorithms. To a certain extent, it addresses the long‑standing EV trade‑off between performance and efficiency.

The two Guinness records correspond to two core user needs: efficient daily commuting and stable handling under aggressive control. That said, high integration is a double‑edged sword – while it drastically reduces part count, it also magnifies repair costs if a core component fails. Looking ahead, 800V plus high‑integration multi‑in‑one e‑drives will be the mainstream BEV path for the next three years. For average car buyers, the Galaxy TT, with this e‑drive, covers both long‑distance travel and urban commuting, making it a competitively positioned choice among 5‑metre‑class BEVs in terms of its electric powertrain.
