Lexus HS 250h – The World’s First Dedicated Luxury Hybrid Car

Lexus 2010 HS 250h

This week announced the latest addition to its entry-luxury sedan line-up, the HS 250h fits nicely between the IS luxury sport sedan and the ES luxury sedan. Research has shown that more than 60 percent of entry-luxury car buyers would have considered a hybrid car if available, and the HS will provide these consumers with a viable purchase option.

Equipped with Lexus’s first four-cylinder petrol engine, the 2.4-litre Atkinson-cycle powerplant is part of the latest Lexus Hybrid Drive System, which generates 187 total system horsepower. The highly efficient Atkinson-cycle engine, made possible by the Variable Valve Timing with intelligence (VVT-i) system, allows the expansion/power stroke to be longer than the compression stroke so that combustion energy can be more effectively used for production of engine power. The HS 250h sedan’s expected fuel efficiency will be more than 30 percent better than the most fuel-efficient model currently in the Lexus lineup, while earning a SULEV emissions rating utilising regular 87-octane petrol. Among the technologies adopted in the 2.4-litre four-cylinder engine are cooling piston oil jets; an optimised balance shaft rate for improved Noise, Vibration and Harshness (NVH) characteristics; and a hot-air venting system mounted behind the radiator.

Converj: The “Cadillac” Of Electric Vehicles

GM Converj Concept

General Motors unveiled a further glimpse at the potential of electric propulsion today, this time in the form of luxury transportation, with the Cadillac Converj Concept. The Cadillac Converj was developed as a well-appointed grand touring coupe with a bold design and a host of interactive technology.

The four-passenger Converj concept is intended to show how GM’s revolutionary electric propulsion technology – called Voltec – can power a luxury coupe with a typically Cadillac “no compromises” design. The technology enables up to 40 miles of gas- and emissions-free electric driving with extended-range capability of hundreds of miles.

Bob Lutz, GM’s vice chairman of Global Product Development, said the Converj concept has production substance. “It’s a logical extension of our plan to reinvent the automobile,” he said. “It clearly shows what a Cadillac electric vehicle could look like, and clearly indicates that global luxury customers can have a car that has both strong design and electric propulsion with a total range of hundreds of anxiety-free miles.” read more »

Tesla Roadster Sport

Tesla Motors Inc. began taking orders today for the Roadster Sport, a high-performance sports car based on the world’s leading all-electric, zero-emission vehicle.

The Roadster Sport does 0 to 60 mph in 3.7 seconds, compared with 3.9 seconds for the standard Roadster. It comes with a hand-wound stator and increased winding density for lower resistance and higher peak torque. In addition to Yokohama’s Ultra High Performance tires, the Roadster Sport has improved suspension with adjustable dampers and anti-roll bars that will be tuned to the driver’s preference.

The Roadster Sport starts at $128,500 in the United States and €112,000 (excluding VAT) in Europe. Deliveries begin in late June. read more »
