Tata Motors, the new owner of Jaguar and Land Rover, has guaranteed at least the next five years of existing product plans. That's a practical decision, if nothing else, because to cancel programs now would bring instant cost penalties.

Here is what AutoWeek expects is coming from Jaguar and Land Rover during the next eight years.

2009

ENLARGE Look for a performance version of the Jaguar XF, shown, in 2009.

New Jaguar XFR, XKR: These high-performance versions of the XF sedan and the XK coupe will be based around an all-new 5.0-liter, direct-injection gasoline V8, in naturally aspirated and supercharged variations. The cars will go on sale late in the year. The naturally aspirated V8 will be rated at 380 hp, and the supercharged version will make about 500 hp. Both will be equipped with ZF's latest seven-speed automatic transmission.

Facelifted Range Rover, Range Rover Sport: These models will get the new 5.0-liter V8s used in the Jaguars. Also, the Range Rover and the Range Rover Sport will get redesigned interiors with revised instrument panels, switchgear and interior trim.

2010

Jaguar XJ (Project X351): This is the overhaul of Jaguar's flagship sedan. With styling inspired by the XF, the new XJ nonetheless will be its own car, with a more restrained, regal air than the racier XF. The dimensions stay the same, but just as Jaguar has cleverly repackaged the old S-Type platform for the XF, careful interior design will create more leg and shoulder room in the new XJ.

Facelifted Land Rover LR3: Just like the Range Rover, the LR3 will get a facelift and an interior revamping. The focus is on much higher interior quality, particularly the instrument panel and center console. We also expect the 380-hp 5.0 V8 to appear.

Jaguar X-Type: This is likely the year for the unloved X-Type to die and make room for the LRX on the Halewood production line.

2011

ENLARGE Land Rover LRX concept

Land Rover LRX (Project L513): This will be the most significant new model in the early stages of Tata's ownership as Land Rover extends its range to six models. Land Rover is striving to retain as much of the LRX concept's interior as possible to fill the vehicle's role as the company's urban chic car and compete against the Mini. A hybrid model is planned. A major question is the name -- LR1 could be too entry-level, but LR4 could be too upmarket.

2012

Jaguar F-Type (Project X700): Jaguar has wanted a $50,000 two-seat sports car since it unveiled the F-Type concept in 2000. Now the car is back in the planning stage, with options to base it on either the XF or XK platform. Tata boss Ratan Tata appears to have given the F-Type his backing. The production car could be badged as the XK-E.

Seven-seat Land Rover LRX (Project L486): Land Rover is planning a new model, possibly with seven seats and possibly a spinoff of the LRX. Details are scarce, but the vehicle will follow the Mini Clubman route and aim for chicness and uniqueness.

2013

ENLARGE Jaguar C-XF concept

Jaguar XF Coupe (Project X252): This is another obvious range extension, but it awaits a green light from Tata. Jaguar has based the design on the lower-roofline style seen on the rakish C-XF concept. But a convertible is unlikely. The XF platform isn't strong enough to cope with an open-roof body. There won't be a wagon variant, either.

All-new Range Rover (Project L405): Thirteen years after Ford bought Land Rover, the flagship that relaunched the company will be replaced. Expect the size to grow but the styling to become sportier and less utilitarian. Bentley levels of luxury are planned, making the $200,000 Range Rover no flight of fancy. Alloy body construction and hybrid powertrains will keep weight and emissions down and fuel economy up.

2014

All-new Jaguar XF (Project X260): This car is likely to bring alloy body construction to the midsize Jaguar, as once planned under Ford. By creating the new XF alongside 2015's new XJ, Jaguar can get vital economies of scale.

All-new Range Rover Sport (Project L494): Created as a variant of the new Range Rover, the new Sport also will switch to an aluminum body.

All-new Land Rover Defender: This is not confirmed, but for developing countries, Tata is eyeing a 4x4 with simple, robust engineering similar to past models of the Toyota Land Cruiser. Sales could add up to hundreds of thousands of units. Some production could be overseas. This could give Land Rover the perfect base to use to replace the Defender.

2015-2016

All-new Jaguar XJ (Project X360): This is already penciled in as a new four-door flagship to replace the 2010 reskinned model.

All-new LR3: It will be time for the seven-seat LR3 to be replaced, but the platform is unknown. Could this be a variant of the new Defender?
