Next Focus ST will likely come with a 2.0 liter turbo EcoBoost dialed up to around 250 bhp (186 kW).

A new Ford Focus ST variant will be debuting at the Paris auto show this October alongside the next-generation Ford Focus, according to AutoExpress.

The next Focus ST will be getting a new EcoBoost engine to replace the rather thirsty 2.5 liter, turbocharged 5-cylinder unit of the previous ST and the current Focus RS.

That engine would likely be an uprated variant of the 2.0 liter turbo EcoBoost with 200 bhp (149 kW) seen in the current Mondeo, Galaxy and S-Max models. That power plant could be tuned to around the 250 bhp mark to match the likes of the Renault Sport Megane 250 and the Golf R with its 266 bhp.

An RS variant of the next-generation Focus could also be derived from that 2.0 liter turbo EcoBoost, dialed up to around the 300 bhp mark.

The next ST will make use of Ford's torque vectoring technology to help balance all that power going through the front wheels to provide as much grip as possible. It's 0 to 100 km/h (62 mph) sprint will be around 6 seconds, top speed around 155 mph/250 km/h and fuel economy will be considerably improved over the previous 2.5 liter unit. Different driving modes will be available with the drive software.

The next-generation Ford Focus hatchback and wagon will go on sale in Europe in April of 2011. The ST will come later in the year.
