MG HS Engine Review: 4 Powertrains Compared For 2025

The MG HS stands out in the competitive mid-size SUV segment with its range of powertrains, blending affordability with practical performance. From the entry-level petrol unit to advanced plug-in hybrids, this review dives into acceleration figures, real-world driving dynamics, fuel efficiency, and how it stacks up on UK roads.

Powertrain Lineup: Options for Every Driver

MG equips the HS with versatile engines catering to budget-conscious commuters and eco-focused families. The core offering is a 1.5-litre turbocharged petrol engine producing 160bhp and 250Nm of torque, paired with either a six-speed manual or seven-speed DCT automatic transmission. This setup delivers respectable figures on paper: 0-62mph in 9.9 seconds and a top speed of 118mph.

For those prioritizing electrification, the plug-in hybrid (PHEV) combines the 1.5-litre petrol with a 120bhp electric motor, yielding 254bhp and 370Nm total. It achieves 0-62mph in 7.1 seconds—noticeably brisker than the petrol—while offering up to 75 miles of electric-only range, ideal for low company car tax. A self-charging hybrid variant adds further choice, boasting around 200bhp combined and claimed 51mpg economy, though real-world results vary. Newer models, like the 2025 2.0T with 170kW (228bhp) and 370Nm via a nine-speed automatic, promise smoother high-speed cruising.

This table summarizes key specs, highlighting the PHEV’s edge in outright performance.

Real-World Acceleration and Responsiveness

While official stats paint an optimistic picture, everyday driving reveals nuances. The 1.5-litre petrol feels adequate for urban pottering but requires aggressive revving beyond 4,000rpm for overtakes, where power fades and engine noise intrudes. Manual versions respond better than the DCT automatic, which adds perceptible lag from junctions.

The PHEV shines here, blending seamless electric torque for instant launches with petrol backup for longer trips. Despite paper claims, it doesn’t always hit 7.1 seconds due to front-wheel-drive traction limits—tyres can chirp under hard acceleration—but it’s markedly quicker than petrol siblings and handles motorway merges effortlessly. The 2.0T variant, as tested in 2025 reviews, delivers linear pull without the smaller engine’s strain, making it suitable for loaded family runs.

• Petrol pros: Smooth low-rev delivery for city use.
• Petrol cons: Noisy at high revs; DCT hesitancy.
• PHEV advantage: EV mode silence up to 75 miles; total output feels potent.
• Hybrid note: Balances power and lower emissions at 126g/km CO2.

Road Handling and Ride Quality

Built on a platform with MacPherson front struts and multi-link rear suspension, the HS prioritizes comfort over sportiness. It absorbs UK potholes decently thanks to soft springing, but body control wanes at speed over uneven surfaces or cambers, leading to wallow in corners.

Steering is light and precise for parking, yet lacks feedback for enthusiastic driving. The PHEV’s extra 275kg weight aids stability on motorways but amplifies understeer if pushed. Rivals like the Ford Kuga offer sharper handling, though the HS counters with value and space. Overall, it’s tuned for family buyers valuing ease over excitement.

Motorway Manners and Refinement

Highway performance is a strong suit. Both petrol and PHEV cruise at 70mph with minimal wind or road noise, quieter than many budget rivals. The petrol unit settles into a refined hum if not overworked, while PHEV EV mode delivers absolute silence. Overtaking demands more effort from the 1.5-litre than the hybrid’s combined grunt, but all variants maintain composure.

“The HS PHEV cruises motorway speeds uncomplainingly, with smooth engine integration.”

Fuel Economy and Efficiency Breakdown

Efficiency varies by powertrain. The petrol achieves 37-40mpg in mixed driving—impressive for its size without hybridization—beating official 38mpg claims in long-term tests. PHEV owners can hit over 100mpg with regular charging thanks to the 75-mile EV range, dropping to 40-50mpg otherwise. Self-chargers claim 51mpg but deliver closer to 45mpg in practice.

CO2 outputs range from 169g/km (petrol) to under 50g/km (PHEV with charge), making the latter tax-efficient for fleets. Real-world factors like traffic and load influence results, but the HS undercuts pricier SUVs.

Comparisons with Key Rivals

Against the Hyundai Tucson or Kia Sportage, the MG HS trails in refinement but leads on price and PHEV range—only the Geely Starray matches it. The Ford Kuga edges handling, yet the HS’s 7-year warranty and lower costs appeal to value seekers.

|Rival|0-62mph|PHEV Range|Price Edge|
|—|—|—|—|
|Ford Kuga|7.5s|50 miles|MG cheaper by £5k|
|Hyundai Tucson|8.0s|62 miles|Similar efficiency|
|Kia Sportage|8.2s|No PHEV base|MG warranty longer|

Long-Term Reliability Insights

Early HS models used proven engines, but newer all-hybrid units introduce unknowns. Long-term tests report solid economy without major issues, though monitoring systems may need frequent resets. MG’s 7-year warranty mitigates risks.

Who Should Choose Which Engine?

• Budget buyers: 1.5L petrol for 40mpg value.
• Fleet drivers: PHEV for tax savings and EV range.
• Balanced needs: Self-charging hybrid for refinement.

Frequently Asked Questions (FAQs)

Is the MG HS PHEV worth it over petrol?

Yes, for low-mileage users leveraging 75-mile EV range and lower taxes; petrol suits high-mileage without charging.

How noisy is the 1.5L engine?

Civilised below 4,000rpm but intrusive when revved hard.

What’s the best transmission?

Manual petrol for responsiveness; DCT for hybrids.

Does it handle well?

Comfort-focused; soft ride but limited cornering poise.

Fuel economy realistic?

Petrol: 40mpg achievable; PHEV: 100+mpg with charges.
