2013 Lexus ES will make the Buick LaCrosse laughable

Article by Christian Andrei, on January 3, 2012

It appears that the upcoming 2013 Lexus GS will make quite a buzz on the market and the Japanese manufacturer is confident that the new vehicle will outscore its market competitors. In fact, a Lexus executive said that the 2013 Lexus ES luxury sedan will make the Buick LaCrosse “laughable” as a luxury vehicle.

Although the executive didn’t want to give too many details, he said that the next-generation ES will be wider and longer than the current model but what is more interesting is the fact that the new ES will be the quietest car Lexus has ever made.

Moreover, the new Lexus ES will offer Hybrid Synergy Drive full-hybrid technology and it will be able to achieve a fuel economy of over 40 mpg on the highway.

For those who don’t know, the Buick LaCrosse eAssist is powered by a 2.4-liter Ecotec four-cylinder engine mated to a new Hydra-Matic 6T40 six-speed automatic transmission.

The eAssist system uses a 115V air-cooled lithium-ion battery which bolsters its power with approximately 11 kW (15 horsepower) of electric power during heavy acceleration and 15 kW of regenerative braking power. The total output of the car is rated at 180 horsepower (134 kW). The Buick LaCrosse eAssist has a fuel consumption of 37 mpg on the highway.

It has been 20 years since the introduction of the Lexus. Good news for its most avid fans as the ES350 and the ES300h -- comprising the sixth generation of this model -- has been introduced.

The ES maintains the Lexus legacy by including the classic spindle grille but has updated the level of comfort, the handling and improved the design. The ES is also available with the Lexus Hybrid Drive and the designers are positive it will win over new customers and impress those who love Lexus.

Mark Templin, the Lexus Group Vice President and General Manager, said that by setting the benchmark for comfort, affordability, overall quality and versatility, the luxury sedan market was forever changed when it introduced the Lexus. Now the ES350 and our ES hybrid are going to change things again.

Engine/Transmission/Drivetrain/Performance

Now available with the Lexus Hybrid Drive for the first time, the ES also comes with a 2.5 liter four-cylinder Atkinson cycle engine. The 300h is capable of generating 200hp and is fully expected to receive the EPA fuel economy rating of roughly 40 mpg depending on whether the ES is used in the city or the highway.

The ES comes with an incredibly advanced power management system and has a high compression ratio of 12.5:1. The low friction engine has been designed to improve overall efficiency and it comes with an electrical water pump, an integrated hybrid electrical motor, power steering and it is belt-less. As the engineers found the removal of the belt aided fuel economy, efficiency and made it much more reliable.

The 3.5 liter V6 engine in the ES350 is capable of 268 hp at 6,200 rpm and it has 248 lb-ft of torque at 4,700 due to the Dual VVT-i. The six-speed automatic transmission is an intelligent (ECT-i) sequential-shift design and has been configured to aid performance, a much smoother shift and fuel economy.

The overall performance and efficiency have been improved by the introduction of a series of low friction materials and have ensured the ES350 can deliver an EPA fuel efficiency of between 21-31 mpg depending on the terrain.

The drive selector mode comes in Eco, Normal and Sport mode with each mode providing a combination of high-performance and efficiency which can aid in fuel economy, enhanced responsiveness in the steering and an increased powertrain in both models. The ES300h has a few additional changes including a tachometer rather than a hybrid power monitor and the 300h has an EV mode for shorter distances which only use the battery pack.
