The answer can be found in VW's latest racing project, the diesel Caddy van. In place of the usual 104bhp 1.9-litre TDI engine, this boasts a 230bhp version of the 2.0-litre TDI powerplant from the MkV Golf. With the help of a bigger turbocharger and intercooler, the racing motor punches out 65 per cent more power than the standard unit.
Yet internally, there are no differences. The pistons, con-rods, bearings, crankshaft and flywheel are identical. For the road-going Golf TDI GT, what could this mean? Although VW won't reveal any details, it confirms that more powerful versions are on the cards.
And that's promising, because the Caddy TDI Racer packs a real punch. If the same philosophy can be applied to VW's road models, then there could be some seriously hot diesels on the way.
