2010 Lexus HS 250h Review Overview

The new 2010 Lexus HS 250h combines the performance of a V6 with the mileage of a four-cylinder economy car using an advanced hybrid gas-electric powertrain.

Hybrid drive systems can be designed to boost mileage as in the Prius or enhance performance as in the LS 460. The Lexus systems are a modular technology and can deliver any mix of the two. The new HS 250h falls somewhere in the middle of the hybrid spectrum.

The result is a clean, efficient luxury car with good numbers both in power and fuel economy. The HS 250h gets an EPA-estimated 35 mpg in combined city and highway driving yet can accelerate from 0-60 mph in a respectable 8.4 seconds. In combination with the hybrid drive motor, the HS 250h generates 187 total system horsepower, running on regular unleaded gasoline.

The Lexus HS 250 doesn't offer the compelling visceral experience that comes with neck-snapping acceleration and high-G-force cornering, but like the Prius, it has technology features that make it a fascinating car to operate. It's a car that appeals more to a finely developed sense of touch. The HS experience is more like driving a laptop, one with a lot of bright, new features and an inviting, intuitive operating system. To operate the HS is to experience a sense of enlightenment, more than a compulsion to drive harder and faster.

This is the first hybrid-only car for Lexus, and the first Lexus with a four-cylinder engine. The 2010 HS 250h offers all the latest hybrid-drive system upgrades that are now spreading through the Lexus line of hybrids. The new systems are lighter, more compact and more efficient.

The HS combines elements of the Prius platform with the more powerful Camry hybrid powertrain. The HS also has the smoother ride and refined features consistent with a car in this price range.

Mileage is equivalent to the Camry hybrid, which is a bigger car but only slightly roomier inside than the HS 250h. Compared to other cars in the Lexus line, the HS is about 5 inches longer than the sporty IS and about six inches shorter than the ES sedan. It's a little bigger, with more legroom in back, than the Mercedes C-Class and BMW 3 Series cars.

Like the Prius, the HS 250h makes a social statement, but does so within the context of a forward-looking, technology-driven luxury brand. Its more powerful 2.4-liter engine is quite a bit peppier than the Prius, consciously trading some mileage for better acceleration and easier highway cruising.

But at 35 mpg overall, the HS 250h is still highly economical and efficient. The HS 250h generates 70 percent fewer emissions than the average new car. It's a California Super Ultra Low Emissions Vehicle (SULEV), which makes it one of a handful of the cleanest cars in the world.

The battery pack is located between the rear seat and trunk, powering a motor generator that adds about 40 horsepower, which is blended into the system according to driver demand. The batteries are automatically recharged as needed, either by the engine or braking action that converts momentum into electricity.

The HS 250h has four drive-modes: Normal, Power, Eco and EV. The different modes alter throttle response, managing fuel flow for more power, or conversely, better economy. The electric-only EV mode has a modest range that varies according to temperature, driver demand and battery condition, estimated at somewhere between half a mile and 1.5 miles.

A well-appointed interior is set up to take advantage of new ideas about how to adjust controls and features without distracting the driver's attention. An available mouse-like controller, the Remote Touch system, eliminates the need for touch screen controls.
