Heat oil in a large pot over medium heat. Add onion, garlic and sauté 4 – 5 minutes, add bacon and sauté 2 minute longer.
Pour vodka and allow to cook off (about 3 minutes). Add tomatoes, tomato paste, sun-dried tomatoes and season with salt and freshly ground pepper. Add basil, mix well, cover and simmer until strong alcohol scent has cooked off, about 10 minutes, stirring occasionally.
Meanwhile cook penne according to package directions.
Stir cream into sauce and let just heat through, about 2 minute. Stir in parmesan, butter and sugar and simmer over low heat for approximately 30 minutes, stirring occasionally to prevent burning.
Season with salt and pepper to taste if needed and serve over pasta.
