The 2016 Vauxhall Insignia with its **Whisper Diesel** engine marks a significant step forward in diesel technology, blending impressive fuel economy, serene cabin noise levels, and practical family-friendly features. This model, particularly the 1.6 CDTi ecoFLEX variant, delivers up to 74.3mpg combined and CO2 emissions below 100g/km, making it a standout for cost-conscious drivers.

Engine Performance and Whisper Technology

At the heart of the 2016 Insignia is the **1.6-litre turbo diesel** engine, producing 136PS (134bhp) and a robust 320Nm of torque. This powertrain earns its “Whisper Diesel” nickname through advanced engineering that minimizes vibration and noise, transforming the typical diesel clatter into a near-silent operation.

Drivers report effortless acceleration, with 0-60mph in 10.9 seconds and a top speed of 130mph. The torque peaks early, providing strong mid-range pull ideal for overtaking on highways without needing frequent gear changes. Real-world testing confirms motorway efficiency exceeding 68mpg, thanks to the engine’s broad torque band that keeps revs low during cruising.

• Torque Delivery: 320Nm available from low revs, ensuring responsive performance in a large saloon or estate body.
• Stop-Start System: Standard feature reduces urban fuel use by shutting off the engine at idle, restarting seamlessly.
• Refinement: 90% of the time, the engine runs smoothly, with minimal intrusion even under load.

Fuel Economy and Environmental Impact

Official figures boast 74.3mpg combined, with real-world averages around 61.4mpg on test drives and up to 60mpg in mixed conditions. This efficiency stems from the ecoFLEX tuning, lightweight materials, and aerodynamic design, positioning the Insignia as a leader in its class for low running costs.

CO2 output of 99g/km qualifies it for low benefit-in-kind tax rates, appealing to company car users. Compared to petrol alternatives like the 1.4 turbo (35-40mpg) or 1.8 VVT (36mpg), the diesel variant shines for high-mileage commuters.
