It’s model-year changeover over time for the Vauxhall Insignia with the British company announcing the addition of a low emissions ecoFLEX diesel model and a new-to-the-range 1.4 Turbo petrol engine.

Beginning with the petrol model, the 1.4-liter turbocharged unit, which is also offered in the Astra, delivers 140-horsepower and 200Nn of peak torque, while returning 51.4mpg UK (5.5 lt/100km) in the hatchback and saloon models and emitting 129g/km of CO2. In the UK, the Insignia 1.4 Turbo is priced from £18,680 for the ES Hatchback up to £27,110 for the SRi Nav Vx Line Red Sports Tourer.

For the new model year, GM’s Vauxhall unit updated the Euro 5 compliant 2.0 CDTi diesel engines in the Insignia ecoFLEX model. The four-cylinder unit is available with 130PS or 160PS power outputs, and for the first time, is offered with Start/Stop technology. The underbody aerodynamic measures and low rolling resistance tires help to improve fuel consumption and CO2 emissions.

When equipped with the 130-horsepower version, the Insignia ecoFLEX achieves a top speed of 129mph (209 km/h), with 0-60mph (96 km/h) taking 10.4 seconds. The 160HP model records a 137mph (220 km/h) top speed and a 0-60mph sprint time of 8.9 seconds. Compared to the outgoing ecoFLEX diesel, CO2 emission have dropped by 10 percent, from 129g/CO2 to 115g/CO2.

Prices for the Insignia ecoFLEX diesel models start from £20,345 for the ES 2.0 CDTi 130PS Start/Stop Hatchback and go up to £29,385 for the top-of-the-range SRi Nav Vx Line Red Sports Tourer 160HP.

It seems the success of the Buick Regal, which is essentially a rebadged Opel Insignia, has determined GM management to consider bringing another Opel to the U.S., the Astra GTC hatch. Buick will soon have a compact sedan in its range, the Astra-based Verano due to be launched this fall, but it also wants a sporty hatchback with enough power and fine handling to lure young buyers.

According to a report from Car & Driver, the Opel Astra GTC is almost certain to come to the U.S. The model will be launched in Europe at the Frankfurt auto show this September and will go on sale shortly after with four-cylinder engines ranging from around 100 horsepower to more than 250 horsepower in the OPC high-performance model.

In the U.S. however, the car is expected to be offered with the same engines found in the Verano, which uses GM’s Delta platform that forms the base for the Astra and the Chevy Cruze: a 2.4-liter four-cylinder engine with 177 horsepower and a turbocharged 2.0-liter four-cylinder with around 220 horsepower. Both engines will be mated to six-speed automatic and manual transmissions. The name that will be used by Buick's version of the Astra GTC is yet unknown.

Aside from the Astra GTC, Buick might also adopt another Opel model that is currently under development, the replacement for the Astra Twin Top coupe-cabriolet. The new convertible will compete against the recently launched VW Golf Cabriolet. If Buick decides to offer the Opel convertible it will become the first Buick droptop since the Reatta

And no, despite what you may have heard or read, the Audi TT ain’t the most popular car among hairdressers – or at least not in Britain. According to a new study made available today by UK women's car insurance specialist Diamond, that title goes to…*drums please*…the one and only, MINI One hatchback. In fact, the BMW Group’s MINI brand had two vehicles in the top five positions.

The UK insurance firm came to this conclusion after looking at data from over 18,000 hairdressers in Britain. The company said the MINI One is three and a half times more likely to be driven by someone working as a hairdresser than everyone else.

Next up on the list are the Vauxhall Tigra, a Fiesta-sized hardtop-convertible from GM’s European arm and Volkswagen’s New Beetle (the outgoing model), both of which are said to be more than three times as popular with hairdressers than the rest of the UK. The fourth and fifth place finishers of the study are the Ford Ka and Mini Cooper.

"It's not surprising that the Mini One is so popular amongst hairdressers, as it's stylish, modern and looks great,” said Diamond managing director, Elwyn Gedrych. “In fact, with two Mini models in the top 5, that certainly cements its place as the ultimate 'hairdresser's car'."

One more finding from the study is that British hairdressers are 33 percent more likely to drive a convertible model than drivers from other professions.

So there you have it. The Mini One is officially the real hairdresser’s car. Have your say in the comments below.
