Barina means big business for US

Sonic is the new name chosen for the Holden Barina in the USA and the four-door sedan is unveiled at the Detroit motor show to highlight a production switch to an American factory. It's a sign that small cars will be big business in the USA inside five years, as well as proof that General Motors is going global at the bottom end of the business.

Sonic will not be used as a name in Australia with the Barina badge to continue on both the new sedan and hatch, a pairing that will sit above the existing Barina Spark. The Barina hatch was first displayed at the Paris motor show last year and the sedan - as the Sonic - starred in Detroit with looks that point to a more upmarket approach to GM's small cars.

"Sonic is a statement of what can be expected of this foundational brand in years to come," says Mark Reuss, the head of Chevrolet and former Holden boss who unveils the car as part of Chevy's 100th birthday celebrations. That approach will be reflected in the price, as the new Barina pair will have a $15,000-ish starting sticker, well up from the basic Barina Spark at $12,490.

"This is Barina and the smaller version is Barina Spark," says Jonathan Rose, spokesman for GM Holden.

"We're getting the sedan and hatch. The hatch will be later this year, around October, and the sedan about this time next year. The cars are coming from Korea. The US will build theirs locally."

There is some impressive stuff in the Spark - yet to be confirmed for Barina - including 10 airbags and a sports suspension system tuned by the team behind Chevrolet's blaster car, the Corvette.

Both cars will come with a 1.6-litre four-cylinder engine and a choice of manual and automatic gearboxes, unlike the Spark that is currently only sold as a manual. GM claims more rear-seat space than the Ford Fiesta and best-in-class boot space for the Barina sedan, as well as youth-essential features such as Bluetooth USB connectivity.

The spirit of the SS Commodore could be tapped for a high-performance Barina. Chevrolet has a Sonic with a turbocharged 1.4-litre engine that makes 102 kiloWatts and a dress-up pack that is being considered for Australia. It is called the Z Spec is only billed as a concept car in Detroit but is clearly intended to put some punch into the Sonic is a country where small cars are still not particularly popular.

GM Holden admits it can see potential in a Z Spec version of the Barina but is not making any commitment.

"The Z Spec is a concept. No decision has been made on whether it will be introduced in Australia. We'll be sure to assess it," says Jonathan Rose.
