Default impala 3.6

My mother is looking at newer impalas which some have the 3.6, but not much info out there yet about reliability and fuel efficiency in real world. sounds good on paper 300hp and 30 mpg but its a caddy motor and that makes me real nervous. anyone have any input or experience?

why do you say it is a Caddy motor because it is OHC ? 300hp from a 3.6 L is nice, that is about 20 HP less than the Impala SS V8 2006.

LFX

The LFX is an enhanced version of the LLT engine. Introduced in the MY2012 Chevrolet Camaro LS, it is 20.5 pounds (9.3 kg) lighter than the LLT, due to a redesigned cylinder head and integrated exhaust manifold, and composite intake manifold. Other components like the fuel injectors, intake valves, and fuel pump have also been updated. Power and torque are up slightly from the LLT. The compression ratio is 11.5:1.

looks like they are using the same 3.6L in the XTS, which they will have a twin turbo 410 hp version, can't find any complaints.... Is this an all new motor design for these platforms for 2014, may be too early.

and the trans was developed with ford, forget it.


6T/6F Manufacturer General Motors/Ford
Production 2006–
Predecessor 4T60-E/4T65-E
4T80-E
AX4N
Class 6-speed transverse automatic transmission

General Motors and Ford Motor Company cooperated in 2002 to create a new automatic transaxle, designed for transverse engine applications in cars and light trucks. The companies jointly committed to investing US$720 million in their manufacturing plants to support the new transmission.

Each company will name and manufacture the transmission separately:

Ford builds the 6F50 and 6F55 at their Van Dyke Transmission Plant in Sterling Heights, Michigan, and in the future at Sharonville Transmission in Sharonville, Ohio.
GM builds the 6T70 and 6T75 at Warren Transmission in Warren, Michigan with production starting in July, 2006.[1]

Ford claims the 6F50 is designed to handle 300 hp (224 kW) and 280 ftlbf (380 Nm), while General Motors rates their 6T70 to 315 hp (235 kW) and 280 lbft (380 Nm) and the 6T75 to 315 hp (235 kW) and 300 lbft (407 Nm).

Ford appears not to have made a public statement regarding the 6F55'* maximum capabilities, but uses it in AWD in the Taurus SHO with an engine rated at 272 kW (370 PS; 365 hp)and 475 Nm (350 lbft) of torque (Final drive 2.77:1).

The first application of the technology is in the 2007 Ford Edge and Lincoln MKX crossover SUVs, as well as the Saturn Aura sedan and the Saturn Outlook crossover. It was also used for the Pontiac G6 GTP models and the GMC Acadia models for 2007. Prior to 2009, this transmission had issues caused by a very weak 3,5,R wave plate, which made this transmission prone to failure in GM products. Updated wave plates were released for many clutches in 6T70. The old design wave plates weren’t stress relieved and could break with use. The updated wave plates are available under the following part numbers:

Why does your mother need 300 HP? Does she rob banks? Not judging, just asking.
