Start of by asking the question a little differently. If you were the big boss what are the top company objectives covering short and long term:
1. Increase market share
2. Increase net revenue
3. Keep customers happy (repeat business)
To meet these objectives, the TLX needs to be revised and fine tuned to be top class in reliability, performance, and features within its price range.
Reliability: we all know the challenges and these are likely first production year. They must be 99% gone for 2016+
Performance: Increase fuel efficiency and give the gear heads a bit more HP. This is not a deal breaker for 75% of the buyers, and 90% of the drivers will never use all that power.
Features: Become a leader with current technology, and provide integration with smart devices that allow user upgrades. This must include performance improvement of processors associated with navigation nanny features as we transition to semi and driverless cars.
SH-AWD on the I4 is a challenge in many ways for Acura as it would be just one more discrete models. SH-AWD with common transmission and controls for both models, eliminating the FWD completely, might be economical (production line, parts, training, etc.). It would raise the bottom end of the price range and differentiate it from the Accord.
Manual transmission does not fit with the long term (or is it medium term) move to semi or driverless cars. This is a costly engineering change for likely less than 10% of the sales, and would be just one more discrete model (does not fit the Acura strategy) IMHO.
