2013 Lexus GS 450h Rated at 34 MPG Highway, GS 350 at 28 MPG

2013 Lexus GS 450h

The 2013 Lexus GS 450h’s fuel-economy estimates beat the automaker’s expectations with an EPA-estimated 29/34/31 mpg city/highway/combined, Toyota announced. That’s about a 35% improvement in gas mileage over the 2011 GS 450h, which gets 22/25/23 mpg. When Toyota officials unveiled the hybrid at the 2011 Frankfurt Motor Show, they expected a 30% improvement over the 2011 model.

Like the previous GS 450h, Lexus promises V-8 power with four-cylinder efficiency. The 338-horsepower hybrid system has two electric motors — one for each rear wheel — and they can power the GS using electric only or in tandem with the 3.5-liter V-6. Overall, Toyota says the 2013 GS 450h should hit zero to 60 mph in 5.6 seconds, which is 0.4 seconds slower than the 2011 GS 450h but 0.1 seconds faster than the 2013 GS 350. The hybrid model gets high- and low-beam LED headlamps and LED taillamps standard. The cabin has a standard climate control system, a bamboo-trimmed steering wheel and a hybrid monitoring system.

Compared with its only competitor, the 2012 Infiniti M Hybrid, which nets a 27/32/29 mpg rating, the Lexus 450h is both more fuel efficient and more powerful.

The redesigned 2013 GS 350 has an EPA-estimated 19/28/23 mpg, a 4.5% increase over the 2011 Lexus GS 350.

The 2013 Lexus GS 350 goes on sale in February, and the 450h will go on sale next spring. Pricing for both models is unavailable.



It's a sad day for Infiniti.


Nissan can add port/direct injection to the VQ35 in the M hybrid. Raising the compression ratio, and increasing efficiency.

Plus the stepped 7 speed automatic is still more fun to drive than the IVT in the Toyota hybrid.

No a fan of "performance" hybrid at all, but Nissan seems to be aiming for performance instead of fuel economy?

M35H seems to have faster acceleration time than the GS450H, when their engines are V6 & V8 respectively...sound strange that it's slower with a larger engine (more powerful too as per article).


Performance hybrids are great, gas guzzlers are depressing. Performance hybrids are guilt free and the technology is exciting
