Chrysler's upcoming 6.4L V8 only for SRT, not for Ram?
2010 Dodge Challenger SRT8

Back in November, during Chrysler's seemingly endless business plan presentation, Ram trucks chief Fred Diaz told the captive media audience that the new 6.4-liter Hemi gasoline V8 would likely appear in Ram's heavy duty trucks. Fast forward to today, however, and it would appear that the big Hemi is now off the table. PickupTrucks.com reports that the 6.4 Hemi will instead be exclusive to Chrysler's potent SRT vehicles. Chrysler VP of product development, Joe Veltri, says that the 6.4 is designed for performance, not the grunt work truck buyers demand of their vehicles.

PickupTrucks.com notes also that Veltri sees a need for Ram to get gas engine that delivers more power and torque than the currently-available 5.7-liter Hemi, but that the likely course of action will involve building off that engine, rather than looking to adapt the SRT lump for truck duty. Why the drive to add more gas offerings in the diesel-dominated heavy-duty truck category? Emissions regulations, natch. Increasingly strict rules mean that diesels are becoming commensurately more costly to produce and sell, and Chrysler sees the ratio of diesel to gas engines offered becoming much closer in future years than it is today. Head over to PickupTrucks.com for the full skinny.

New York 2010 Preview: All-new 2011 Kia Optima
2011 Kia Optima

The next stage of Kia's transformation from design also-ran to serious contender will kick off at the New York Auto Show in few weeks. After launching the Forte sedan and Koup, the new Sorento and, most recently, the Sportage, Kia's new design language is being applied to the Optima. The all-new 2011 Kia Optima is longer, wider and lower than the car it replaces although we don't know by how much. While it's not as aggressive as the sketches released a few weeks ago, this Optima is certainly a huge step forward.

We don't have any mechanical details yet, but we'd guess that the Optima shares a lot under the skin with the new Hyundai Sonata. Nor would we be at all surprised to learn that the Optima won't have a V6 engine option this time around. Instead, it'll probably use the same direct-injected 2.4-liter inline-four found in the Sonata. The turbocharged and hybrid variants may follow as well.

Officially Official: Lotus, Cosworth back in the IndyCar series
Lotus-Cosworth/KV Racing IndyCar

Lotus is officially returning to the IndyCar series in 2010 in partnership with engine builder Cosworth and KV Racing. Lotus, as you well know, has a long history with Indy-style open-wheel racing, dating back to the early 1960s. Its exploits include a victory by Jim Clark in 1965 and the all-wheel-drive, turbine-powered cars that arrived a few years later.

A few weeks ago, Lotus announced a revival of its cooperation with Cosworth for both road and race cars. The new collaboration with KV is described as being both technical and commercial. It's not clear at this point what Cosworth will contribute from a technical perspective, since all the current IndyCars run Honda V8s. Perhaps KV will provide a platform upon which Cosworth can test and develop a new engine for the next-generation IndyCar regulations that are in the works.

The green and yellow Lotus/Cosworth-badged car will debut in two weeks at the St. Petersburg, Florida race with ex-Honda F1 pilot Takuma Sato at the controls
