The Astra Xtreme, a concept car presented at the 2001 Geneva motor show, was a single-production V8-powered Astra based on the G-series Astra DTM. Like the DTM racing car, it featured a 4.0 litres (240 cu in) V8 engine , producing 444 hp (331 kW), gull-wing doors supported by gas struts, carbon fibre panels, and race-specification interior with ...
The GM Family I is a straight-four piston engine that was developed by Opel, a former subsidiary of General Motors and now a subsidiary of PSA Group, to replace the Vauxhall OHV, Opel OHV and the smaller capacity Opel CIH engines for use on small to mid-range cars from Opel/Vauxhall.
The second generation Family 0 began production in November 2002. It is an updated version of the Family 0 engine and features TwinPort technology – twin intake ports with a choke closing one of the ports at low RPM, providing strong air swirl pattern for higher torque levels and better fuel economy.
This is a list of Saturn vehicles, or vehicles produced by the Saturn Corporation, a former subsidiary of General Motors. The list spans vehicles from 1990 to 2009, [ 1 ] with concept vehicles as early as 1984.
The second generation of the Saturn VUE, introduced in 2007 for the 2008 model year, was a rebadged version of the German-designed Opel Antara, manufactured in Mexico. After the demise of the Saturn brand, the VUE was discontinued, but the car continued to be produced and sold as Chevrolet Captiva Sport in Mexican and South American markets.
It was to debut in the 2009 Saturn Vue Hybrid, where it would have made 262 hp (195 kW; 266 PS) at 6100 rpm and 250 lb⋅ft (339 N⋅m) of torque at 4800 rpm. [14] Fuel economy ratings would have been 6–8 km/L (17–23 mpg ‑imp ; 14–19 mpg ‑US ) in city, and 9–11 km/L (25–31 mpg ‑imp ; 21–26 mpg ‑US ) on highway.
Saturn inspired a cult following with annual 'meetings' in Tennessee of Saturn owners, as well a day-to-day special events in retail settings. However, the division never made a profit and by the 2000s was a several billion dollar loss for General Motors, which due to its massive financial problems closed the 'experiment' and folded Saturn back ...
Pogo oscillation is a self-excited vibration in liquid-propellant rocket engines caused by combustion instability. [1] The unstable combustion results in variations of engine thrust, causing variations of acceleration on the vehicle's flexible structure, which in turn cause variations in propellant pressure and flow rate, closing the self-excitation cycle.
