Vauxhall Astra Start/Stop


Each year car makers focus more on one of the fuel saving technologies more than others! Last year it was direct injection, and this year it seems to be the auto Start/Stop systems as more and more companies are offering that on at least one of their models.

Here’s Vauxhall’s start/stop-enabled Astra which on the paper offers some amazing numbers taking the edge over the competition. The Astra 2.0CDTi equipped with this system has average fuel consumption of over 60 MPG while it does 0 o 60 mph in 8 seconds. You rarely get that combination in a car in this segment.

The addition of start/stop system not only improved the fuel economy by 13 percent it’s also lowered the CO2 emissions from 129g/km to 119g/km.

What’s more this version is also going to be very tax friendly, so you get most of your money back at the pumps and at during its lifetime.

The Astra 2.0 CDTi Start/Stop 5-dr Hatch and Sports Tourer are available to order now. The model replaces the outgoing Astra 2.0 CDTi and is only available with manual transmission (a 2.0 CDTi auto model is also available without Start/Stop).

Pricing for the 5-door Hatch starts at £22,410 for the SRi model, and £23,430 for the Sports Tourer SRi. The 2.0 CDTi Start/Stop can also be ordered in SE and Elite trims (Hatch) and SE (Sports Tourer).

With a 0-60mph time of just 8.5 seconds and combined mpg of 62.8, the new Astra 2.0 CDTi Start/Stop Hatch really is a case of having your cake and eating it.

By adding Start/Stop tech to the existing Astra 2.0 CDTi Hatch, Vauxhall has not only maintained the model’s robust performance, but reduced its fuel consumption and CO2 emissions, too. Compared with the outgoing 2.0 CDTi Hatch, the Start/Stop version’s fuel consumption improves by over 5mpg on the combined cycle, from 57.6mpg to 62.8mpg. Naturally, drivers will experience the biggest fuel consumption gain around town, where Start/Stop has meant a gain of 13 per cent on the urban cycle.

Better still, for business users, Start/Stop tech on the Astra 2.0 CDTi Hatch has dropped CO2 emissions from 129g/km to 119g/km, meaning that the model’s BIK rate (percentage of the car’s price to be taxed) for standard rate tax-payers is down by five per cent to 13 per cent. And both private and business users will benefit from the Start/Stop’s lower VED band, which will save them £65 each year (down from £95 to £30).

Start/Stop is also available on the latest addition to the Astra range, the Sports Tourer, which benefits from an equally impressive 4.7mpg rise on the combined cycle, from 55.4 to 60.1mpg.

The Astra 2.0 CDTi Start/Stop also incorporates Vauxhall’s CleanTech Combustion Technology, which guarantees exceptionally clean combustion and reduces engine noise, too. CleanTech is a closed-loop system which adjusts fuel injection to the combustion process in real time. Combined with reduced friction camshaft bearings, the system ensures that the engine runs more quietly and efficiently.

Start/Stop – Vauxhall’s pain-free solution to lower-emissions motoring

Vauxhall’s automatic Start/Stop system reduces the engine’s time spent idling, and therefore the car’s overall emissions and fuel consumption, especially during town driving. The engine automatically stops when the driver engages neutral and releases the clutch pedal, sending it into ‘Autostop’ mode. When the vehicle needs to move away again, the driver simply presses the clutch to re-start the engine and engages first gear.

For safety reasons, and for passenger comfort, the temperature regulator and brake booster vacuum control remain active in Autostop mode. And if circumstances require – for example, in start-stop traffic – the driver can manually deactivate the system using the ‘eco’ labelled Start/Stop switch.

In order for Start/Stop to function, certain criteria have to be met. The engine needs to be up to full operating temperature, and the battery needs to be sufficiently charged. The outside temperature also needs to be above freezing and the Defrost function not activated.

Apart from these parameters, the Start/Stop system includes the following ancillaries:

  • A more robust starter motor
  • A high performance battery, which ensures maximum reliability of the electrical system and the engine’s capacity to start without delay
  • An intelligent battery control with sensor, providing reliability and consistent quality
  • An energy management system responsible for trouble-free re-starting of the engine.

Start/Stop tech to roll out across almost all of Vauxhall’s car lines

The introduction of Start/Stop for ecoFLEX models is part of Vauxhall’s ongoing strategy to reduce fuel consumption and emissions across its fleet. The system first appeared in the Corsa 1.3 CDTi ecoFLEX model last year, allowing the car to retain its healthy performance from its 95PS engine, yet reducing emissions to 94g/km for the 3-door model (making it the most economical production Vauxhall in the company’s history) and boosting its combined fuel consumption to 80.7mpg.

By Spring 2012, most of Vauxhall’s model lines will feature Start/Stop technology on ecoFLEX models, including many petrol-engined cars too.
