For 2012, the SRX gets an upgrade of main propulsion system that could increase sales even more. The standard 265-hp, 3.0-liter V-6 is dead. New customers should be relieved not to have to turn your engine up to 5. 100 rpm just to access a limp 223 pounds-feet of torque. Also on 3. 0 liters will be a relief is relieved of the weight of 4500 lbs SRX is slow. Cadillac stopped offering previously optional SRX engine, a turbocharged 2.8-liter V-6, earlier this year. Few mourned the loss of the CV-300, a single turbo six. His praise was filled, probably with reference to the turbo lag, linear power delivery, and the origins of Saab.
When two become one
Replacement of the two engines is a single 3.6-liter V-6. "This is the engine of the SRX should have had all the time," said an engineer who declined to be identified. The engine is similar to the 3.6-liter V-6 found in the CTS, but has been adapted and adjusted to transverse arrangement of the SRX. Some changes, such as exhaust manifolds Intelligence built into the head, plastic intake manifold, lighter and connecting rods help shave 20 pounds off the 3.6-liter V-6. Lightening rods allows the engine a little higher speed, and high speed driving at 308 hp at 6800 rpm. Other changes, such as additional sound deadening on the firewall and an intelligent rubber insulated high pressure fuel line, keep engine noise to the cabin. Putting rubber between the fuel line and the engine almost eliminates the ticking sound injector we have come to expect from the direct injection engine at idle.
The six-speed automatic transmission moves from the previous 3.0-liter V-6, but his team has undergone a complete rehabilitation. In normal mode, upshifts and downshifts the transmission to be expected. Move the shift lever to the left to access sport mode. In sports, the transmission has more gears, a lower gear before, and refuses to move the main gear. The manual control is available, if you find that the way sport is not like it, but found the work very well in the northeast of the canyon roads of Santa Barbara, California. A fourth mode of transmission is accessed by a button labeled "eco" located next to the shifter. Select echo, and the transmission shifts to fuel-conscious algorithm, which seeks to upshift and resists downshifts early (eco mode also decreases the sensitivity of the accelerator, but were forced to notice the difference). Cadillac claims a 1 mpg increase is possible in eco mode. According to EPA, the front-wheel drive SRX will achieve 17 mpg city and 24 on the road, one on each test worse than the 2011 model 3.0-liter and one of the few drawbacks of this engine change. All wheel drive versions come in 16/23, which has dropped one in the city cycle compared to the 3.0 liters. Compared with turbo V-6, 3.6 liters of improvement of 1 mpg in city and highway cycles, and the new V-6 does not require premium fuel as it did last year turbo.
With 265 lb-ft of torque available from 2400 rpm, the 3.6-liter does not have to work as hard as the 3.0 liter SRX move from a stop. The torque curve is almost flat from 2400 rpm to 5300 rpm, making for a smooth and seamless acceleration. We hope that the new match engine or nearly match the V-6 turbo 7.2 seconds from 0 to 60 time. Even when lashed to its maximum power 6. 800 rpm, the V-6 continues to be refined and pleasant. There is an appropriate amount of peak intake and exhaust growl. The endless strain of 3.0 liters is gone.
About this cover
Other changes are minor in the SRX. The cargo area can set up a rail system similar to that found in the Mercedes-Benz products, the switches have migrated to lock the doors to combat allegations of JD Power in relation to the center console mounted lock / unlock the switch-despite a redundant switch remains in the center console, a heated steering wheel comes in all but the base trim level, Bluetooth is standard on all trim levels, and there is a new design 20-inch wheel and a new ebony interior has white contrast stitching on the seats and dashboard. The exterior of razor full of potatoes in the SRX is unchanged.
Two suspension settings are available. Most versions come with the basic agreement FE2 that has two tubes of small bumps and roll bars that the FE3 sports suspension. SRXs equipped FE3 get active downloads to adjust stiffness according to the condition of the vehicle speed, load, address, and the road, variable power steering, which contracts at high speed, and 20-inch wheels and thinner accompany the tire sidewalls. Transmission slippage in sport mode also makes shocks in a more sporty and more rigid. Both suspensions have the same spring rates. Although the roll control is a bit better with the FE3 suspension, there is a huge benefit in sporty feel and handling, and it would be very difficult to pay extra for it. Either way, the SRX makes the Lexus RX feels like a cluttered mess.
