The LF-Gh Concept, a car that will likely form the inspiration for Lexus' next-generation GS, is set to dominate the marque's stand at July's Australian International Motor Show in Melbourne. First seen at the New York Auto Show in April, the edgy hybrid-powered concept debuts an aggressive, spindle-shaped grille flanked by narrow LED headlamps, which Lexus says indicates the direction of all future Lexus designs. The design is also said to represent the next stage in Lexus' L finesse design philosophy, which debuted in 2001, with hints of the brand's LFA supercar and IS-F road car clearly evident in its dramatic outline. "The LF-Gh grille really is a powerful design element in its own right - it will become a signature Lexus design element," said Lexus Australia chief executive Tony Cramb. "Our latest vehicle, the CT 200h, hinted at where we were taking our L finesse design philosophy, but LF-Gh leaves no questions about what is next for Lexus. "The grille is more than just a design element; it also plays a substantial role in airflow control and stability. "Much like in the case of the Lexus LFA supercar, the designers and engineers for the LF-Gh concept have used function to inspire and mould the design of a spectacular-looking vehicle," Mr Cramb said. Its designers say LF-Gh Concept aims to blend style, performance, efficiency and environmental compatibility, while at the same time leveraging advanced and new technologies. It's expected the road going version will offer a petrol-electric hybrid version in addition to conventionally-powered V6 and V8 engines. Measuring 4890mm long, 1870mm wide and 1450mm high, the concept is 40mm longer, 50mm wider and 20mm taller than the current GS, suggesting the replacement model will offer more interior space. The show model omits door handles and wing mirrors to retain a cleaner look, though these will be likely inclusions come production time. The interior will likely be unveiled at the Tokyo International Motor Show in December. The Australian International Motor Show opens at 6pm on Friday 1 July and runs through until Sunday 10 July at the Melbourne Convention and Exhibition Centre.
