The Rivière, Pontiac’s midsize crossover VEHICLE, concluded production in the summer of 2009. Remaining yify 4k provide the choice of 3. 4-liter and 3. 6-liter V-6 engines.
The base Bit-torrent makes use of the 3. 4-liter LNJ engine, with 185 horsepower in addition to 210 lb-ft of torque. This kind of 12-valve, iron-block pushrod V6, today manufactured in China, is definitely a old design. Its standard architecture dates back in order to 1980, although GM refurbished this thoroughly in this early nineties, with lightweight aluminum cylinder heads, roller rocker arms, together with an aluminium intake a lot more. For last year, it gotten a range of minor changes to be able to strengthen dependability, including more durable sphincter muscle seats, chromed and lustrous valve comes, and a new revised electronic throttle control system. Typically the 3. 4-liter engine’s electric power is not really remarkable with regard to this class, although it provides Torrent adequate speeding. Superior revs betray their age group with a gruff sound and experience, nevertheless that has great low-end revolt and good gas economic climate. EPA reports are 17/24 for each FWD and AWD designs.
The particular Rivière GXP, added inside 2008, uses this very much more sophisticated 3. 6-liter LY7 engine. This all-aluminum, 24-valve DOHC V6 will be part of GM’s “High Feature” engine family, created by way of GM and their Australian part, Holden. Initially seen inside the Cadillac CTS sedan 7 years ago, the idea possesses variable valve timing to both the intake and exhaust cams, and variable-length intake runners to optimize twisy at various engine speeds. In the Torrent GXP, they have 264 horsepower (up coming from 263 in 2008) together with 250 lb-ft regarding revolt. The high-tech V-6 shows the Torrent much more robust efficiency, although some testers complain which it sounds even coarser and less refined in comparison with the elderly 3. 4-liter pushrod V6. Additionally, it burns a little more fuel; often the FWD Torrent GXP fits the 3. 4-liter’s 17/24 ENVIRONMENTAL PROTECTION AGENCY rating, but typically the 4WD version falls to help 16/24. Both engines melt away standard fuel.
