The Vauxhall Insignia 2.0 CDTi ecoFLEX represents a smart choice in the midsize car segment, blending strong diesel performance with impressive fuel savings and low emissions. This model, available in hatchback and estate variants, appeals to company car drivers, families, and long-distance commuters who prioritize running costs alongside comfort and space.

Engine Performance and Fuel Efficiency

At the heart of the ecoFLEX Insignia is a 2.0-liter CDTi diesel engine offered in 138bhp or 160PS tunes. The 138bhp version delivers respectable acceleration with a 0-60mph time around 9-10 seconds, while maintaining official combined fuel economy figures as high as 76.3mpg and CO2 emissions as low as 99g/km. Real-world testing often yields 50-60mpg, making it a standout for budget-conscious owners.

Key efficiency enhancements include low-rolling-resistance tires, aerodynamic tweaks like lowered suspension and underbody panels, and optimized gearing that keeps engine revs low—around 1,600rpm at motorway speeds. These changes reduce CO2 by up to 20g/km compared to standard models without compromising power.

This table summarizes key specs from various trims, highlighting the ecoFLEX’s edge in economy.

Driving Dynamics and Ride Comfort

Despite its focus on efficiency, the Insignia ecoFLEX handles everyday driving with poise. Revised suspension components, including lighter bushes, control arms, and retuned dampers, improve ride quality, especially on larger 18-inch wheels. The electric steering feels more precise, allowing confident cornering, though the car’s weight limits sporty ambitions.

Reviewers note a comfortable cruiser for motorways, with minimal cabin noise and vibration at low revs. It’s not as agile as a Ford Mondeo but excels in absorbing bumps and providing stability on long hauls. Start-stop technology aids urban efficiency, and optional FlexRide adaptive suspension further enhances versatility.

  • Smooth low-rev torque: Pulls strongly from 1,600rpm without strain.
  • Refined ride: Larger wheels improve composure over rough roads.
  • Motorway poise: Quiet and stable at 70mph+ speeds.

Interior Space and Practical Features

The Insignia’s cabin impresses with generous space for five adults and a large boot—over 500 liters in the hatch, expanding significantly in the Sports Tourer estate. Materials feel solid, with supportive seats and ample adjustment. Ambient lighting, plentiful overhead lamps, and intuitive controls create a welcoming environment.

Tech highlights include sat-nav, DAB radio, Bluetooth, climate control, and IntelliLink infotainment with USB/aux inputs. Safety aids like forward collision alert and automatic emergency braking add peace of mind, scanning roads ahead and applying brakes if needed.

Practical touches abound: heated mirrors, auto lights/wipers, cruise control, and LED daytime running lights. However, some note the small screen between gauges flashes frequent warnings during initial drives.

Running Costs and Ownership Appeal

Low CO2 ratings (99-136g/km) slash benefit-in-kind tax for company drivers, often matching or undercutting rivals. Fuel savings can exceed £600 annually versus non-eco models, assuming average diesel prices. Insurance and maintenance remain reasonable, with strong residuals for diesel variants.

Equipment levels are generous from entry trims: 17-inch alloys, leather steering wheel, and no spare tire (inflation kit standard—consider adding a spare). At around £21,000-£25,000 new, it offered great value, packing premium-like features.

Safety and Reliability Insights

The Insignia scores well in safety, with standard collision mitigation systems proving effective in urban and highway scenarios. Diesel engines prove durable, with high-mileage examples (140k+ miles) maintaining fit and finish. Common checks include diesel particulate filter health and suspension wear.

Ideal Buyer Profile

This ecoFLEX model suits fleet managers, families needing estate space, and efficiency-focused private buyers. It’s less ideal for keen drivers seeking razor-sharp handling, but punches above its weight in value and low running costs.
