Ward's seems to think that one of those vehicles will be the new RX crossover, one of the brand's most popular (and oldest) offerings. The complete and utter lack of spy photos of the new RX doesn't necessarily support Ward's argument, although if the new CUV ends up being based on the JDM Toyota Harrier, as previously reported, the absence of camouflaged images might make some sense.
As for that other vehicle, it's hard to say what we might see. Were we to put our money on it, though, the long-awaited GS F would be a strong contender for a Detroit debut. The high-performance challenger to the BMW M5 and Mercedes-Benz E63 AMG has been spotted almost completely undisguised as recently as October. On top of that, Detroit's reputation as a performance-focused show (last year's show saw debuts of the Ford Mustang, BMW M3 and M4, Chevrolet Corvette Z06, Volkswagen Golf R and Porsche 911 Targa) makes the GS F's appearance there a fair bet.
One thing we can count on at least hearing about when Detroit rolls around is Lexus' strong sales position. The company's 2014 sales should crest 305,000 units by the end of the year, marking the first time the company had passed the 300,000-unit mark since 2007. Bracken told Ward's that should be an easy task, particularly with the brand's "best month of the year," December, still to come.
