INTRODUCTION
The Opel Insignia Grand Sport (B) 1.6 CDTI EcoTEC 110 hp, launched in 2017, represented a key offering in Opel’s lineup. It was designed to appeal to buyers seeking a spacious, comfortable, and fuel-efficient hatchback. This variant sat towards the lower end of the Insignia range, providing an accessible entry point into the model. The “Grand Sport” designation signified the hatchback body style, differentiating it from the later “Sports Tourer” (estate/wagon) versions. The engine, a member of Opel’s EcoTEC diesel family, was intended to deliver a balance between performance and economy, making it suitable for both daily commuting and longer journeys. This model was a significant part of Opel’s strategy to modernize its image and compete effectively in the competitive D-segment.
Powertrain & Engine Architecture
The heart of this Insignia variant is the B16DTE engine, a 1.6-liter inline-four cylinder diesel. This engine is a member of Opel’s ‘EcoTEC’ diesel range, known for its focus on efficiency and reduced emissions. It utilizes a common-rail direct fuel injection system, operating at very high pressures to atomize the fuel for cleaner combustion. The engine is turbocharged with a variable geometry turbocharger (VGT) and intercooled, which helps to improve both power and torque delivery. The engine features a Double Overhead Camshaft (DOHC) valvetrain with four valves per cylinder, optimizing gas flow for improved performance. The 110 hp version of this engine was specifically tuned for fuel economy, with a lower power output compared to higher-spec versions. The engine is paired with a six-speed manual transmission, chosen for its efficiency and driver engagement. The transmission’s gear ratios are optimized to provide a balance between acceleration and fuel consumption, with a relatively long final drive ratio to enhance highway cruising efficiency.
Driving Characteristics
The 1.6 CDTI EcoTEC 110 hp Insignia Grand Sport delivers a competent, if not particularly exhilarating, driving experience. Acceleration from 0-60 mph takes around 11 seconds, which is adequate for everyday driving but noticeably slower than higher-powered Insignia variants. The engine produces a respectable 300 Nm (221 lb-ft) of torque at 2000 rpm, providing sufficient pulling power for overtaking and climbing hills. However, the engine can feel strained when pushed hard, particularly when fully loaded. The six-speed manual transmission is well-matched to the engine, offering smooth gear changes and a reasonable spread of ratios. The steering is precise and well-weighted, providing good feedback to the driver. The suspension is tuned for comfort, absorbing bumps and imperfections in the road surface effectively. Compared to the more powerful 1.6 CDTI (136 hp) or the 2.0-liter petrol variants, this version prioritizes fuel economy over outright performance.
Equipment & Trim Levels
The 1.6 CDTI EcoTEC 110 hp Insignia Grand Sport typically came equipped with a reasonable level of standard equipment. This included air conditioning, a touchscreen infotainment system with Bluetooth connectivity, alloy wheels, and a suite of safety features such as ABS, ESP (Electronic Stability Program), and multiple airbags. Interior upholstery was typically cloth, with a dark color scheme. Optional extras included heated seats, a panoramic sunroof, a navigation system, and advanced driver assistance systems such as adaptive cruise control and lane departure warning. Trim levels varied depending on the market, but generally, this engine was offered in mid-range trims, providing a good balance of features and affordability. The dashboard layout was modern and functional, with a clear instrument cluster and intuitive controls.
Chassis & Braking
The Insignia Grand Sport’s chassis features an independent McPherson strut suspension at the front and a multi-link suspension at the rear, providing a comfortable and controlled ride. The front brakes are ventilated discs, offering good stopping power, while the rear brakes are solid discs. The steering system is an electric power-assisted rack and pinion system, providing precise and responsive steering. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering. The weight distribution is well-balanced, contributing to the car’s stability and handling. The standard tire size is 225/55 R17, providing a good compromise between grip and ride comfort.
Market Reception & Comparison
The 1.6 CDTI EcoTEC 110 hp Insignia Grand Sport was generally well-received by critics as a practical and fuel-efficient option. However, some reviewers noted that the engine lacked the punch of higher-powered alternatives. Fuel economy was consistently praised, with combined figures of around 4.0 l/100 km (58.8 US mpg) being achievable in real-world driving. Compared to the 1.6 CDTI 136 hp version, the 110 hp model offered lower running costs but sacrificed some performance. Against petrol-powered rivals, the diesel engine provided superior fuel economy, but at the expense of refinement and potential maintenance costs associated with diesel particulate filters. The Insignia Grand Sport as a whole was seen as a strong competitor in the D-segment, offering a spacious interior, comfortable ride, and competitive pricing.
Legacy
The B16DTE engine, while generally reliable, has been known to exhibit issues with the diesel particulate filter (DPF) if not driven on longer journeys regularly. The engine’s timing chain is another potential area of concern, requiring periodic inspection and potential replacement. However, with regular maintenance and careful driving, this powertrain can prove to be durable and long-lasting. On the used car market, the 1.6 CDTI EcoTEC 110 hp Insignia Grand Sport represents a relatively affordable option for buyers seeking a spacious and fuel-efficient hatchback. Its practicality and reasonable running costs make it a popular choice for families and commuters. The Insignia Grand Sport, in general, has established itself as a well-regarded and dependable vehicle, and this variant continues to offer good value for money.
