MG HS Fuel Consumption and Efficiency Guide

The MG HS is more than just an affordable SUV—it’s a balance between performance, comfort, and modern hybrid efficiency. Whether you’re considering the petrol-powered MG HS or the plug-in hybrid MG HS PHEV (EHS), understanding its fuel consumption, CO₂ emissions, and overall efficiency is key to making an informed decision. Let’s break down how each generation performs under real-world and WLTP testing conditions.

MG HS Fuel Consumption Overview

The MG HS lineup offers both traditional petrol engines and a plug-in hybrid powertrain, allowing buyers to choose between spirited driving and eco-friendly efficiency. Below we detail the official WLTP figures across model years.

MG HS 2026 (Petrol Models)

• Minimum WLTP Consumption: 7.4 L/100 km
• Maximum WLTP Consumption: 7.6 L/100 km
• Minimum CO₂ Emissions: 168 g/km
• Maximum CO₂ Emissions: 173 g/km

The 2026 petrol version maintains an efficient range for a mid-size SUV, thanks to refined turbocharging and improved engine calibration.

MG HS 2023–2024 (Plug-in Hybrid)

• Fuel Consumption (WLTP): 1.8 L/100 km
• CO₂ Emissions (WLTP): 43 g/km
• Powertrain: 1.5 T GDI + electric motor (258 PS combined output)

The plug-in hybrid variant—marketed as the MG EHS—delivers exceptional economy, particularly for urban commuting. Its hybrid setup allows short electric-only trips while retaining petrol performance for longer journeys.

MG HS 2020–2023 (Plug-in Hybrid)

• Fuel Consumption (WLTP): 1.8 L/100 km
• CO₂ Emissions (WLTP): 43 g/km
• Variants:
  • EHS Comfort 258 PS
  • EHS Luxury 258 PS

Both trims share identical efficiency ratings, differing mainly in interior and equipment upgrades rather than mechanical setup.

Understanding MG HS Engine Options

Petrol Engines

The 1.5-litre turbocharged petrol engine is a key player in MG’s lineup. Delivering around 169 PS, it balances performance and reasonable consumption. Paired with either a 6-speed manual or 7-speed DCT, it ensures smooth shifts and predictable driving behavior.

Plug-in Hybrid System

The EHS Plug-in Hybrid combines the same 1.5 T GDI engine with an electric motor and a 10.1 kWh lithium-ion battery.

• Electric-only range: approximately 32 miles (WLTP)
• Total system power: 258 PS
• Transmission: 10-speed automatic hybrid gearbox

This blend allows drivers to commute emissions-free for short distances while retaining robust long-haul capability.

MG HS CO₂ Emission Breakdown

The table highlights just how efficiently the plug-in hybrid performs—emitting roughly 75% less CO₂ than its petrol-only sibling.

Efficiency by Driving Cycle

Urban Driving

The hybrid model thrives in stop-and-go traffic, often running exclusively on electric power. Expect consumption well below 2 L/100 km in city conditions.

Highway Driving

Petrol models average around 7.5 L/100 km on motorways, while the hybrid transitions smoothly between electric and petrol modes to maintain efficiency.

Combined Cycle

Under WLTP combined testing:

• Petrol: 7.4 – 7.6 L/100 km
• Plug-in Hybrid: 1.8 L/100 km

Real-World Fuel Economy

While WLTP provides standardized data, real-world driving introduces variables such as load, terrain, and climate. On average:

• Petrol MG HS: 8.0 – 8.5 L/100 km (35 – 37 mpg UK)
• MG EHS PHEV: 3.5 – 4.5 L/100 km (62 – 80 mpg UK), depending on electric use.

MG HS Fuel Tank and Range

The hybrid’s range benefits greatly from its electric contribution, making it ideal for drivers seeking long stretches between refueling.

Charging the MG EHS Hybrid

• Battery: 10.1 kWh lithium-ion
• Charging Time (7 kW wall box): ~3 hours
• Charging Time (standard plug): ~6 hours

When fully charged, the hybrid can cover short commutes purely on electricity—perfect for urban users aiming to reduce fuel costs.

MG HS Efficiency Compared to Rivals

While slightly less frugal than some competitors, the MG HS PHEV’s lower purchase price makes it an excellent value-to-efficiency ratio.

How Driving Style Impacts Consumption

• Gentle acceleration maximizes electric range.
• High speeds increase petrol reliance.
• Use of EV mode in traffic reduces CO₂ output dramatically.
• Frequent charging keeps hybrid consumption near WLTP values.

Maintenance Factors Affecting Efficiency

Regular maintenance ensures consistent consumption figures:

• Keep tyres at optimal pressure (36 psi front / 33 psi rear).
• Replace engine oil and filters on schedule.
• Maintain battery cooling system efficiency in hybrid models.

Environmental Benefits

Choosing the MG EHS Plug-in Hybrid means:

• Up to 70% less fuel in city driving.
• Access to low-emission zones.
• Lower annual vehicle tax in most markets.

Final Thoughts

The MG HS continues to evolve as a practical, stylish, and efficient SUV.

• The 2026 petrol variant delivers stable fuel economy for traditional drivers.
• The EHS plug-in hybrid redefines efficiency with near-silent EV operation and minimal emissions.

Both models deliver robust value for money, and with MG’s expanding technology suite, future versions are poised to become even cleaner and more refined.
