[VX_Rules]

Thanks for clarifying

Hi

Im interested in the Arena Focus ST but it doesnt seem that it is a Focus ST afterall given that the Focus ST road car uses the Volvo 2.5 turbo. turbos arent permitted in the BTCC so what engine is in the Arena motorsports cars?

The C30 in the STCC (soon to be BTCC and maybe WTCC) uses a volvo 2.0 5 cylinder non-turbo.

I can't remember the exact rules to this but the road going VXR Vectra uses a 2.8l V6!!! so I think as long as the manufacturer has a 2.0l engine in its stable it is ok (which obviously Ford do)

[LiamM]

The engine used for racing has be based on a production version in the manufacturers range, for example, a few cars have had 1.8l bored out to 2.0

[Rollo]

so what engine is in the Arena motorsports cars?

S2000 rules mandate that the capacity of the engines is restricted to 2000cc. As I already said, the engine in the Ford range that complies with the regulation is the Duratec 20 (Code 993).

The C30 in the STCC (soon to be BTCC and maybe WTCC) uses a volvo 2.0 5 cylinder non-turbo.

The C30 in the STCC (soon to be BTCC and maybe WTCC) does not use a Volvo 2.0 5 cylinder non-turbo because such an engine is not currently in production. The 2.0L engine in the Volvo C30 is the Duratec 20 (Code 993).

The 5 cylinder Volvo engines in the start with the B5244S which is 2.4L and would therefore be excluded or the B524T2 which is 2.5L and turbocharged and would therefore be excluded.

no no, the C30 uses Volvo's 2.0 5 cylinder engine

Currently in production in the Volvo S60 albeit with a turbo.

Volvo Cars develops a new racing car for STCC
- C30 Green Racing

Volvo Car Corporation has decided to develop a completely new racing car and to continue its work with bioethanol (E85) and Green Racing in the STCC (Swedish Touring Car Championship) for three more years.

"Our decision is based on the positive attention and the good results that the recently concluded STCC season has meant for Volvo's brand," says Derek Crabb, head of Powertrain and Engine at Volvo Cars and the man recently appointed to lead Volvo's Racing department.

"It is now time to take the next step for the coming STCC seasons, and to meet the growing international interest in green racing", says Derek Crabb.

Volvo Cars will do this by developing a new and modern green racing car based on the Volvo C30. The C30 is the model that most clearly demonstrates Volvo's environmental technology on the market, with versions such as the Flexifuel and the upcoming 1.6D Efficiency. The Volvo 1.6D Efficiency has an average fuel consumption of 0.45 litres per 10 km (52 mpg-US/62 mpg-UK) and CO2 emissions under 120 grams per kilometre.

"The decision to leave this year's racing car, a Volvo S60, was fairly simple. The Volvo C30 is a somewhat smaller and more agile car with excellent driving characteristics, even in the standard version," says Derek Crabb.

"Development of the new racing car will be done jointly by Volvo Cars and Polestar Racing, who has successfully handled our participation in STCC for several years. However, it is currently too soon to provide any detailed information about the construction of the new car. The objective, on the other hand, is crystal clear - we will develop a winning car," Derek Crabb concludes.

The S60 is the only volvo currently available with the 2.0 5 cylinder engine. What happens when the S60 is replaced in 2010 I wonder?

NB The S40s raced with a volvo 2.0 5 cylinder too but that car was never offered with that engine in production

[shimon340]

Current S60 uses B5204T5

2.0 turbo 5 cylinder

[LiamM]

The S40s where under super touring regs tho, which were very different

[Rollo]

Currently in production in the Volvo S60 albeit with a turbo.

The S60 Turbo from 2001-2003 had the B5234T3 which was 2.3L inline-5. It was replaced with the B5244S. If indeed it is a 2.0L inline 5, then it has to be either a de-bored or de-stroked 2.3 or 2.4. Currently the S60 has either a 2.3, a 2.4 or a 2.5. The 2nd-gen S60 is likely to be fitted with a 2.5L I5 or a 3.2L I6

The S40 for the road was equipped with a B4204T3 which although still came off of the Volvo Modular T5 engine, was only 4 cylinders.

quote "Currently the S60 has either a 2.3, a 2.4 or a 2.5"
