The direct-injection 1.6-litre engine was first seen in the Cascada convertible
The Vauxhall Astra GTC is now available with a new 1.6-litre engine producing 197bhp.
The four-cylinder, direct-injection petrol engine is the same unit used in the Vauxhall Cascada convertible, and comes with 221lb ft of torque. Vauxhall says that when equipped with the new engine option, the Astra GTC becomes the most powerful non-VXR model in the Astra range.
Equipped with the 1.6-litre option, the GTC has a top speed of 143mph and can reach 0-60mph in 7.3 seconds. By comparison, the current Astra VXR achieve the same benchmark in 5.9 seconds and has a top speed of 155mph.
The new engine features engineering improvements to reduce noise, vibrations and harshness as well as twin balancer shafts for smoother running.
Vauxhall says that both power and torque have increased by up to 30 per cent over the outgoing turbocharged 1.6-litre Astra GTC, while the model has improved economy and emissions figures, at 51mpg and 154g/km respectively.
The manufacturer is also introducing its Intellilink infotainment system to the Astra GTC range, priced from £855. The system features satellite navigation and Bluetooth audio functions shown on a seven-inch touchscreen display.
The 1.6-litre Astra GTC is available to order now, with prices starting at £20,995 and with deliveries expected in the spring.
