I love Forza 4 and here is nice review on game credit to jalopnik.com:
With Forza Motorsport 3, Microsoft's Turn 10 Studios tried creating the greatest racing game of its generation. Arguably, it was. On October 11th, when Forza Motorsport 4 is released for Xbox 360 they're setting their sights higher — creating the next generation of car enthusiasts.
Graphics (Polygon count size does matter!): For starters, Turn 10's re-rendered every single vehicle, ripping the graphics engine down and building it back up. And the results are simply staggering. Polygons per car are up from Forza 3's 400,000 to over one million polygons per car in Forza 4. Turn 10's added real-light changes like blooming and lens flares help make the cars look like they're really in the environment. Forza 4 is achieving in real-time at 60 frames per second what was once something Pixar needed weeks to render. Just take a look through the gorgeous gameplay shots in the gallery to the left to see what I mean. It's beautiful.

Physics Engine (Kick the tires and light the fires!): Not only has Turn 10 rebuilt the physics engine from scratch, they've also tried to address one of the most glaring problems with Forza 3, the tires. That's why, for enthusiasts anyway, the most important addition to the game is going to be the tire physics. Thanks to a partnership with Pirelli, Turn 10 has completely redone the modeling for tire dynamics. The tire company let them inside their testing system to give the game a soup-to-nuts data download and allow them to directly input it into the game.

That means that when you turn off all the nanny systems, and you're in a car fitted with a set of racing slicks, and you push down the accelerator a touch too hard, you'll slip and slide in the most realistic way I've ever experienced. I found out embarrassingly first-hand in a simulator the perils of such a setup on a ham-fisted and lead-footed auto journalist.

But it's so brilliantly realistic you can't not be excited at the prospect of turning off the nanny systems and letting loose some tire-shredding burnouts on a digital skidpad. Or, in my case, skidding into walls on an all-new track that Forza tried to build to be the best driving road on Earth. Set in the Swiss Alps with three to five different ribbons, it's certainly intimidating. It's also beautiful to look at.
