Vauxhall Cascada

Powerful new engine to debut in Cascada

Autozine
8 August 2013 | With 200 PS, 300 Nm torque and a top speed of 146 mph, a high-performance version of the new 1.6 SIDI turbo engine is to make its world premiere in a Vauxhall Cascada at next month's Frankfurt Motor Show. The engine is one of the newly-designed Vauxhall four-cylinder SIDI (Spark Ignition Direct Injection) units. It joins the existing 170 PS 1.6 SIDI turbo fitted to the Cascada from its launch earlier this year.
 

The new 200PS 1.6-litre SIDI turbo not only delivers 11 per cent more power, but also 300 Nm maximum torque with overboost – 70 Nm more than the comparable 1.6-litre turbo predecessor, an increase of 30 per cent. With this the Cascada reaches a top speed of 146 mph.

At the heart of the SIDI turbo is a new engine block that can withstand a maximum combustion pressure of up to 130 bar in the cylinder. The block is made of grey cast iron with an aluminium baseplate. In contrast to the 170 PS version, a different type of piston was developed for the 200 PS model and the compression ratio was reduced from 10.5 to 9.5:1. Vauxhall engineers also achieved a high power output with exceptional refinement by optimising the car's induction and exhaust systems.

The new 1.6 SIDI turbo with 200 PS completes the Cascada engine portfolio, with three petrol powertrains. It joins the 1.4 turbo 140 PS as well as the 170 PS 1.6-litre petrol direct injection unit. On the diesel side, the 2.0-litre turbo diesel with 165 PS and the 195 PS 2.0 BiTurbo CDTI are available.

The 200PS petrol direct injection unit is part of Vauxhall's model and powertrain offensive. Within five years, the manufacturer will introduce 23 new models to the market. The Cascada 1.6 SIDI turbo with 200PS and six-speed manual transmission can be ordered from October.
