One of the biggest draws of the Opel Astra CDTI 1.7 is its impressive fuel efficiency. Diesel
engines inherently provide better mileage compared to their petrol counterparts, and the
Astra’s 1.7 CDTI is no exception. Drivers can expect fuel consumption figures in the range
of 50 to 60 miles per gallon (mpg) under mixed driving conditions. Additionally, Opel has
engineered the CDTI engine to meet stringent Euro emission standards, making it a
greener choice for environmentally conscious consumers.
Driving Experience and Handling
Driving the Opel Astra CDTI 1.7 offers a blend of comfort and agility, which is essential for
a compact car competing in a crowded segment.
Ride Comfort and Suspension
Thanks to a well-tuned suspension setup, the Astra CDTI 1.7 strikes a nice balance
between absorbing bumps and maintaining composure during cornering. The front
MacPherson struts and rear torsion beam axle work harmoniously to provide a smooth
ride without sacrificing handling precision. This makes it a comfortable companion for
daily commutes as well as longer road trips.
Steering and Maneuverability
The Astra's steering system is responsive and offers good feedback, which enhances
driver confidence. Whether navigating tight city streets or cruising on the motorway, the
car feels poised and easy to control. Its compact dimensions combined with a tight turning
circle make parking and maneuvering in urban environments hassle-free.
