Nissan Micra DIG-S Review: Efficient 1.2L Supercharged

The Nissan Micra DIG-S stands out in the crowded supermini segment by introducing a supercharged 1.2-liter three-cylinder petrol engine that prioritizes fuel economy without sacrificing drivability. Official figures boast 68.9 mpg combined and just 95 g/km CO2 emissions, making it a leader among petrol-powered rivals. This model appeals to urban commuters and budget-conscious buyers who demand low running costs alongside practical performance.

Engine Technology: Supercharging for Smarter Power

At the heart of the Micra DIG-S is Nissan’s Direct Injection Gasoline Supercharged (DIG-S) powerplant, a 1.2-liter unit producing 97 bhp and 142 Nm of torque. Unlike traditional superchargers that constantly boost power, this system intelligently decouples under light loads, switching to a Miller cycle for superior efficiency. This allows the engine to achieve diesel-like economy from a petrol base.

Key innovations include direct fuel injection for precise combustion, reduced internal friction via diamond-like carbon coatings on components, and an on-demand oil pump. An intelligent alternator charges the battery only during deceleration, further enhancing fuel savings. The result is a smooth, responsive engine that hums quietly at low speeds and whistles engagingly when the supercharger engages around 3000 rpm.

• Power output: 97 bhp @ high revs
• Torque: 142 Nm, available progressively
• 0-62 mph: 11.3 seconds
• Top speed: 112 mph

Real-world testing confirms strong economy: urban 56.5 mpg, extra-urban 78.5 mpg, with drivers reporting over 40 mpg even in mixed conditions. The CVT automatic variant achieves up to 55.4 mpg in tests, though it emits slightly more CO2 at 115 g/km.

Performance and Driving Experience

Despite its economy focus, the Micra DIG-S delivers lively acceleration without turbo lag. The supercharger provides seamless power from mid-range revs, making it ideal for city overtakes and motorway cruising. Reviewers praise its throttle-adjustable handling, which feels agile thanks to a light 980 kg kerb weight and precise steering with a tight turning circle.

On twisty roads, the engine’s character shines: a deepening note and surge between 3000-4000 rpm transform it from efficient cruiser to engaging partner. However, it requires revs to unlock full potential, pairing best with the five-speed manual gearbox despite its occasionally notchy feel. Motorway refinement is good, though fuel use rises under heavy loads.

Running Costs and Ownership Benefits

With VED band A (£0 road tax) and 10% company car tax (2011/12 rates), the Micra DIG-S minimizes ownership expenses. Priced from £11,150 for the Visia trim, it offers strong value in insurance group 8. Low CO2 qualifies it for London Congestion Charge exemption, a boon for city drivers.

Equipment levels are generous even on base models: air conditioning, electric windows, and stop-start tech come standard. Higher trims like Tekna add climate control and alloys, blending practicality with refinement. Servicing follows Nissan’s affordable schedule, supported by a reliable reputation.

Design and Interior Practicality

The Micra’s modern styling ditches the previous model’s quirkiness for a bolder look with sharp lines and a compact footprint. Inside, space is surprisingly generous for a supermini: five doors ease access, and rear seats accommodate adults on short trips. Boot capacity suits family shopping, expandable via 60/40 splits.

Build quality impresses with solid plastics and intuitive layout. The adjustable steering wheel and supportive seats enhance comfort during long drives. Visibility is excellent, aided by large mirrors and a high seating position.

Safety and Reliability Insights

Nissan equips the Micra with six airbags, ABS, and stability control as standard. Euro NCAP ratings (from contemporary models) awarded four stars, with strong adult protection. The lightweight chassis and precise brakes contribute to confident handling in emergencies.

Long-term reliability is a Nissan strength; the DIG-S engine’s advanced tech has proven durable in reviews, with minimal issues reported. Regular maintenance keeps it trouble-free.

Pros and Cons at a Glance

• Pros: Exceptional fuel economy, low emissions, engaging engine, agile handling, affordable costs
• Cons: Needs revs for max power, basic manual gearbox, less cute styling than predecessor

Who Should Buy the Nissan Micra DIG-S?

Ideal for fleet buyers, commuters, and first-time owners prioritizing mpg over outright speed. It outshines non-hybrid rivals in efficiency while matching fun factor. Families may prefer rivals with more space, but for solo or couple use, it’s a smart pick.
