MG Car Electric and Petrol Models Compared: Which One Wins?

When it comes to choosing a new car, the debate between electric and petrol powertrains has never been more relevant. MG Motor, a brand with a rich heritage that dates back to the 1920s, is now at the forefront of this automotive revolution. Originally known for its classic roadsters and sports cars, MG has reinvented itself in the 21st century as a forward-thinking, tech-savvy automaker offering a compelling range of both MG car electric and petrol models. With the UK government’s push toward net-zero emissions by 2050 and the impending ban on new petrol and diesel vehicles by 2030, MG has strategically positioned itself to cater to both traditional drivers and eco-conscious buyers.

Whether you’re a city commuter seeking low running costs or a family driver needing practicality and range, MG’s current lineup offers something for everyone. From the all-electric MG4 to the petrol-powered MG ZS, the brand blends affordability, modern design, and cutting-edge technology. But how do these two powertrains truly compare? Is an electric MG worth the upfront investment, or does a petrol model still make more sense for your lifestyle? In this comprehensive comparison, we’ll dive deep into performance, cost, ownership experience, environmental impact, and long-term value to determine which side of the MG car electric and petrol divide comes out on top.

1. Performance and Driving Experience

Electric Models: Instant Power and Smooth Acceleration

One of the standout advantages of MG car electric models is their performance. Electric motors deliver maximum torque from a standstill, resulting in lightning-quick acceleration and a smooth, silent ride. Take the MG4 EV, for example. The Long Range model (77 kWh battery) can sprint from 0 to 60 mph in just 6.1 seconds, rivaling some hot hatchbacks in its class. The instant power delivery makes city driving effortless, with responsive handling and minimal lag when pulling away from traffic lights.

The MG ZS EV, MG’s compact SUV, offers similar benefits. With a 0–60 mph time of around 8.2 seconds, it’s not a sports car, but it feels agile and confident on urban roads. Electric vehicles (EVs) also benefit from a low center of gravity due to the heavy battery pack mounted beneath the floor, which improves cornering stability and reduces body roll.

Petrol Models: Proven Reliability and Driving Engagement

On the other side, MG’s petrol-powered models like the MG ZS and MG HS offer a more traditional driving experience. The 1.5L turbocharged engine in the MG ZS produces 160 bhp and delivers a 0–60 mph time of approximately 8.5 seconds—slightly slower than the electric variant but still respectable. Petrol engines provide a familiar auditory feedback, with a satisfying engine note under acceleration, which many drivers still appreciate.

Petrol models also tend to be lighter than their electric counterparts (the MG ZS weighs around 1,350 kg vs. the ZS EV at 1,580 kg), which can translate to slightly better fuel efficiency and more engaging handling on winding roads. For drivers who enjoy the tactile feel of a gearshift and the revving of an internal combustion engine, petrol MGs offer a more “connected” experience.

Real-World Driving Scenarios

• City Commuting: Electric MGs shine here. The MG4’s regenerative braking system recovers energy when slowing down, extending range and reducing brake wear. In stop-and-go traffic, the quiet cabin and smooth power delivery make for a stress-free commute.
• Highway Driving: Petrol models may have a slight edge on long motorway journeys. With no range anxiety and faster refueling (5 minutes at a petrol station vs. 30–60 minutes for a 10–80% charge), petrol MGs are more convenient for long-distance travel, especially if charging infrastructure is limited.
• Hilly or Rural Routes: Electric motors handle gradients well due to constant torque, but range can drop significantly in cold weather or when climbing steep hills. Petrol engines, while less efficient uphill, don’t suffer from the same range degradation.

2. Cost of Ownership: Upfront Price, Running Costs, and Incentives

Upfront Purchase Price

When comparing MG car electric and petrol models, the initial price tag is often a deciding factor. Generally, electric MGs have a higher upfront cost due to battery technology. For example:

• MG4 EV (Standard Range): Starts at £25,995
• MG ZS EV (Standard Range): Starts at £30,495
• MG ZS (1.5T petrol): Starts at £23,495
• MG HS (1.5T petrol): Starts at £25,995

As you can see, the petrol versions are typically £2,000–£5,000 cheaper at launch. However, this gap is narrowing as battery costs decline and government incentives kick in.

Running and Maintenance Costs

Where electric MGs truly excel is in long-term running costs. Here’s why:

• Fuel/Energy: Charging an MG4 at home (using a 7.4 kW wallbox) costs around £6–£8 for a full charge (50–60 kWh), giving a range of 200–280 miles. That’s roughly 3–4p per mile. In contrast, the MG ZS petrol averages 45 mpg. With petrol at £1.50 per litre, that’s about 13–15p per mile—over three times more expensive.
• Servicing: Electric vehicles have fewer moving parts. No oil changes, spark plugs, or exhaust systems to maintain. MG offers a 7-year/80,000-mile warranty on EVs, including the battery. Petrol models have a similar 7-year warranty but require regular servicing every 10,000 miles, adding £300–£500 annually.
• Road Tax: Fully electric MGs are exempt from UK Vehicle Excise Duty (VED), saving £180+ per year. Petrol models pay £180 annually after the first year.
• Insurance: EVs can be slightly more expensive to insure due to higher repair costs, but MG’s competitive pricing and safety features (like ADAS on newer models) help keep premiums in check.

Government Incentives and Grants

The UK government offers a Plug-in Car Grant (PICG) of up to £2,500 for eligible EVs under £32,000—meaning the MG4 qualifies, but the ZS EV does not (as of 2023). Additionally, businesses can claim 100% first-year capital allowances on EVs, and company car drivers benefit from a 2% Benefit-in-Kind (BIK) tax rate for electric vehicles (vs. 25–37% for petrol models). These incentives can save thousands over the ownership period.

3. Range, Charging, and Refueling: Practicality for Everyday Life

Electric MG Range and Real-World Performance

Range anxiety is a common concern, but modern MG car electric models are increasingly capable. The MG4 Long Range boasts a WLTP range of up to 281 miles, while the ZS EV Long Range offers 273 miles. In real-world conditions (mixed driving, air conditioning, and hilly terrain), expect 200–240 miles—still sufficient for most daily commutes and weekend trips.

However, cold weather can reduce range by 20–30%. Using heated seats and steering wheel (instead of cabin heating) helps preserve battery life. Pre-conditioning the car while still plugged in (available via the MG iSmart app) is another smart tip to maximize range on cold mornings.

Charging Infrastructure and Speed

Charging an electric MG is straightforward but requires planning:

• Home Charging: A 7.4 kW wallbox charges the MG4 from 10% to 80% in ~7 hours. Ideal for overnight charging.
• Public Charging: At a 50 kW fast charger, the MG4 can recharge from 10% to 80% in ~45 minutes. The ZS EV supports up to 100 kW, reducing this to ~30 minutes.
• Ultra-Rapid Charging: Some newer MG models (like the MG4 XPOWER) support 140 kW charging, cutting 10–80% times to under 30 minutes.

Tip: Use apps like Zap-Map or PlugShare to locate nearby chargers and check availability. MG also partners with charging networks like Ionity and BP Pulse for discounted rates.

Petrol Refueling: Convenience and Accessibility

Petrol models win hands-down in refueling convenience. With over 8,000 petrol stations across the UK, you’re never more than a few miles from a refill. Filling a 45-litre tank in the MG ZS takes 5 minutes and provides 400+ miles of range. No waiting, no app downloads, no compatibility issues.

For long-distance travelers or those in rural areas with sparse charging networks, petrol MGs remain the more practical choice—especially for spontaneous trips or holiday drives.

4. Environmental Impact: Emissions, Sustainability, and Long-Term Footprint

Tailpipe Emissions and Air Quality

The most obvious environmental benefit of MG car electric models is zero tailpipe emissions. In cities like London, where ULEZ (Ultra Low Emission Zone) charges apply, EVs are exempt, saving £12.50 per day. Even outside ULEZ areas, EVs contribute to cleaner air by eliminating NOx, CO2, and particulate matter at the point of use.

Petrol MGs, while meeting Euro 6 standards, still emit CO2 (around 135–145 g/km for the ZS and HS). Over a 10,000-mile annual mileage, a petrol MG emits ~1.4 tonnes of CO2, compared to zero for an electric MG (assuming grid charging).

Lifecycle Emissions and Battery Production

However, EVs aren’t emission-free when considering the full lifecycle. Battery production is energy-intensive, and mining for lithium, cobalt, and nickel raises ethical and environmental concerns. Studies suggest EVs “pay back” their carbon debt after 15,000–20,000 miles of driving (vs. petrol cars), depending on the electricity grid’s cleanliness.

The UK’s grid is increasingly renewable (over 40% in 2023), making EVs cleaner over time. MG also sources batteries from suppliers with sustainability certifications, and the brand is investing in battery recycling programs.

Long-Term Sustainability

• EVs: As renewable energy grows and battery tech improves (e.g., solid-state batteries), the environmental advantage of electric MGs will only increase.
• Petrol Models: While cleaner than older vehicles, they’re on a sunset path. With the 2030 ICE ban, resale value may decline, and future maintenance could become more expensive as parts become scarce.

5. Resale Value, Technology, and Future-Proofing

Depreciation and Resale Value

Historically, petrol cars held better resale value, but the EV market is changing rapidly. According to CAP HPI, the MG4 EV retains ~55% of its value after three years, outperforming many competitors. The ZS EV holds ~50%, while petrol MGs average 45–50%. As EV adoption grows, demand for used electric MGs is rising, especially in urban areas.

Tip: Opt for higher-spec models (e.g., MG4 Trophy or ZS EV Long Range) to maximize resale appeal. These trims often have better battery health and more desirable features.

Technology and Features

Electric MGs often come with more advanced tech as standard:

• MG iSmart App: Remote climate control, charge scheduling, and vehicle tracking (standard on EVs, optional on petrol models).
• Advanced Driver Assistance Systems (ADAS): EVs like the MG4 include adaptive cruise, lane-keeping assist, and automatic emergency braking. Petrol models offer similar features but often at higher trim levels.
• Infotainment: Both electric and petrol MGs feature 10.1-inch touchscreens with Apple CarPlay and Android Auto, but EVs get over-the-air (OTA) updates for software improvements.

Future-Proofing Your Purchase

With the 2030 ICE ban looming, buying an electric MG is a future-proof choice. Petrol models may face restrictions in low-emission zones, higher taxes, and reduced resale value. Electric MGs, on the other hand, will likely see improved infrastructure, longer range, and better performance with each new model year.
