Saab to Premier New 2.3t BioPower Engine in July
27 June 2006
|The E100 Biopower Hybrid will also appear at the British Motor Show in July.|
GM’s Saab will introduce its new 210 hp 2.3t BioPower engine in the Saab 9-5 Saloon and Estate range at the British International Motor Show in London in July. The new 2.3t BioPower model promises 14% more maximum power and 11% more torque, while cutting fossil CO2 emissions by up to 70% when running on E85 than on gasoline. (Earlier post.)
The new Saab 9-5 2.3t BioPower model goes on sale in the UK, Ireland and Nordic markets later this year, with other European countries to follow. Available with manual or automatic transmission, it is being offered in addition to the current 2.0t BioPower model.
Running on E85, the new Saab 9-5 2.3t BioPower engine delivers maximum power of 210 hp (157 kW) and 229 lb-ft (310 Nm) of torque, compared to 185 hp (138 kW) and 207 lb-ft (280 Nm) when using gasoline. As an example of the increased performance, the sedan with manual transmission accelerates from zero to 100 kph (0-62 mph) in 7.9 secs and 80-120 kph (50-75 mph) in fifth gear in 11.0 secs, compared to 8.5 and 12.6 secs when running only on gasoline. (Figures are provisional, pending homologation.)
Saab is also bringing its E100 Saab 9-3 Convertible BioPower Hybrid Concept—unveiled earlier this year in Stockholm—to the British show. (Earlier post.)
This flex-fuel hybrid represents a different approach to a hybrid drive than taken in GM’s current three announced production hybrid systems: the two-mode hybrid in full-size SUVs, the mild hybrid in the Saturn VUE and the micro-hybrid in the Silverado and Sierra.
Combining a 260 hp (191 kW) 2.0-liter turbo BioPower engine that can run on pure ethanol (E100) and two electric motors totalling 53 kW, the BioPower Hybrid Concept can briefly generate torque values three times greater than its gasoline-only equivalent.
The new modular hybrid system features a maintenance-free, 300-volt Li-ion battery pack designed to last the lifetime of the vehicle, a 38kW rear-mounted electric motor, a 15 kW integrated starter/generator (ISG) and all-wheel-drive with electric power transmission to the rear wheels.
The hybrid offers an electric-only Zero Mode for city driving, and has been the subject of intense speculation over whether or not it has an as-yet unannounced plug-in hybrid capability. GM reportedly will introduce a plug-in concept at the Detroit International Auto Show in January 2007. (Earlier post.)
Saab is also bringing its Aero X Concept Car for a debut in London. The two-seater sports coupé runs on E100, and delivers 400 bp (298 kW) maximum power at 5,000 rpm and 369 lb-ft (500 Nm) of torque between 2,000 and 5,000 rpm. (Earlier post.)
